<section id="sn-ArchSpecificPPC"> <title>PPC Specifics for Fedora</title>
<para> This section covers any specific information you may need to know about Fedora Core and the PPC hardware platform. </para>
<section> <title>PPC Hardware Requirements</title>
<section> <title>Processor and Memory</title>
<itemizedlist> <listitem> <para> Minimum CPU: PowerPC G3 / POWER4 </para> </listitem> <listitem> <para> Fedora Core 5 supports only the ���New World��� generation of Apple Power Macintosh, shipped from circa 1999 onward. </para> </listitem> <listitem> <para> Fedora Core 5 also supports IBM eServer pSeries, IBM RS/6000, Genesi Pegasos II, and IBM Cell Broadband Engine machines. </para> </listitem> <listitem> <para> Recommended for text-mode: 233 MHz G3 or better, 128MiB RAM. </para> </listitem> <listitem> <para> Recommended for graphical: 400 MHz G3 or better, 256MiB RAM. </para> </listitem> </itemizedlist>
<section> <title>Hard Disk Space Requirements</title>
<para> The disk space requirements listed below represent the disk space taken up by Fedora Core 5 after installation is complete. However, additional disk space is required during installation to support the installation environment. This additional disk space corresponds to the size of <code>/Fedora/base/stage2.img</code> (on Installtion Disc 1) plus the size of the files in <code>/var/lib/rpm</code> on the installed system. </para>
<para> In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space. </para>
<para> Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation. </para> </section> </section>
<section> <title>The Apple keyboard</title>
<para> The <code>Option</code> key on Apple systems is equivalent to the <code>Alt</code> key on the PC. Where documentation and the installer refer to the <code>Alt</code> key, use the <code>Option</code> key. For some key combinations you may need to use the <code>Option</code> key in conjunction with the <code>Fn</code> key, such as <code>Option</code> - <code>Fn</code> - <code>F3</code> to switch to virtual terminal tty3. </para> </section>
<section> <title>PPC Installation Notes</title>
<para> Fedora Core Installation Disc 1 is bootable on supported hardware. In addition, a bootable CD image appears in the <code>images/</code> directory of this disc. These images will behave differently according to your system hardware: </para>
<itemizedlist> <listitem> <para> Apple Macintosh </para> <para> The bootloader should automatically boot the appropriate 32-bit or 64-bit installer. </para> <para> The default <code>gnome-power-manager</code> package includes power management support, including sleep and backlight level management. Users with more complex requirements can use the <code>apmud</code> package in Fedora Extras. Following installation, you can install <code>apmud</code> with the following command: </para> <itemizedlist> <listitem> <screen>su -c 'yum install apmud'</screen> </listitem> </itemizedlist> </listitem> <listitem> <para> 64-bit IBM eServer pSeries (POWER4/POWER5) </para> <para> After using Open<emphasis role='strong'/>Firmware to boot the CD, the bootloader (yaboot) should automatically boot the 64-bit installer. </para> </listitem> <listitem> <para> 32-bit CHRP (IBM RS/6000 and others) </para> <para> After using Open<emphasis role='strong'/>Firmware to boot the CD, select the <code>linux32</code> boot image at the <code>boot:</code> prompt to start the 32-bit installer. Otherwise, the 64-bit installer starts, which does not work. </para> </listitem> <listitem> <para> Genesi Pegasos II </para> <para> At the time of writing, firmware with full support for ISO9660 file systems is not yet released for the Pegasos. However, you can use the network boot image. At the Open<emphasis role='strong'/>Firmware prompt, enter the command: </para> <itemizedlist> <listitem> <screen>boot cd: /images/netboot/ppc32.img</screen> </listitem> </itemizedlist> <para> You must also configure Open<emphasis role='strong'/>Firmware on the Pegasos manually to make the installed Fedora Core system bootable. To do this, set the <code>boot-device</code> and <code>boot-file</code> environment variables appropriately. </para> </listitem> <listitem> <para> Network booting </para> <para> You can find combined images containing the installer kernel and ramdisk in the <code>images/netboot/</code> directory of the installation tree. These are intended for network booting with TFTP, but can be used in many ways. </para> <para> <code>yaboot</code> supports TFTP booting for IBM eServer pSeries and Apple Macintosh. The Fedora Project encourages the use of <code>yaboot</code> over the <code>netboot</code> images. </para> </listitem> </itemizedlist> </section> </section> </section> </article>

<para> The following CPU specifications are stated in terms of Intel processors. Other processors, such as those from AMD, Cyrix, and VIA that are compatible with and equivalent to the following Intel processors, may also be used with Fedora Core. </para>
<itemizedlist> <listitem> <para> Minimum: Pentium-class ��� Fedora Core is optimized for Pentium 4 CPUs, but also supports earlier CPUs such as Pentium, Pentium Pro, Pentium II, Pentium III, and compatible AMD and VIA processors. Fedora takes this approach because Pentium-class optimizations actually result in reduced performance for non-Pentium class processors. In addition, scheduling for Pentium 4 processors, which make up the bulk of today's processors, is sufficiently different to warrant this change. </para> </listitem> <listitem> <para> Recommended for text-mode: 200 MHz Pentium-class or better </para> </listitem> <listitem> <para> Recommended for graphical: 400 MHz Pentium II or better </para> </listitem> <listitem> <para> AMD64 processors (both Athlon64 and Opteron) </para> </listitem> <listitem> <para> Intel processors with Intel�� Extended Memory 64 Technology (Intel�� EM64T) </para> </listitem> <listitem> <para> Minimum RAM for text-mode: 128MiB </para> </listitem> <listitem> <para> Minimum RAM for graphical: 192MiB </para> </listitem> <listitem> <para> Recommended for graphical: 256MiB </para> </listitem> </itemizedlist>

<section id="sn-ArchSpecificx86_64"> <title>x86_64 Specifics for Fedora</title>
<para> This section covers any specific information you may need to know about Fedora Core and the x86_64 hardware platform. </para>
<note> <title>x86_64 Does Not Use a Separate SMP Kernel</title>
<para> The default kernel in x86_64 architecture provides SMP (Symmetric Multi-Processor) capabilities to handle multiple CPUs efficiently. This architecture does not have a separate SMP kernel unlike x86 and PPC systems. </para> </note>
<section> <title>x86_64 Hardware Requirements</title>

<section> <title>RPM Multiarch Support on x86_64</title>
<para> <emphasis role='strong'>RPM</emphasis> supports parallel installation of multiple architectures of the same package. A default package listing such as <code>rpm -qa</code> might appear to include duplicate packages, since the architecture is not displayed. Instead, use the <code>repoquery</code> command, part of the <code>yum-utils</code> package in Fedora Extras, which displays architecture by default. To install <code>yum-utils</code>, run the following command: </para> <screen> su -c 'yum install yum-utils' </screen> <para> To list all packages with their architecture using <code>rpm</code>, run the following command: </para> <screen> rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n" </screen>
<para> You can add this to <code>/etc/rpm/macros</code> (for a system wide setting) or <code>~/.rpmmacros</code> (for a per-user setting). It changes the default query to list the architecture: </para> <screen> %_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch} </screen> </section> </section> </section> </article>

<para> Beat writers produce the release notes directly on the Fedora Project Wiki. They collaborate with other subject matter experts during the test release phase of Fedora Core to explain important changes and enhancements. The editorial team ensures consistency and quality of the finished beats, and ports the Wiki material to DocBook XML in a revision control repository. At this point, the team of translators produces other language versions of the release notes, and then they become available to the general public as part of Fedora Core. The publication team also makes them, and subsequent errata, available via the Web. </para> </section> </section> </article>

<section id="sn-I18n"> <title>Internationalization (i18n)</title>
<para> This section includes information related to the support of various languages under Fedora Core. </para>
<section> <title>Input Methods</title>
<para> SCIM (Simple Common Input Method) has replaced IIIMF as the input method system for Asian and other languages in Fedora Core in this release. SCIM uses <code>Ctrl-Space</code> as the default trigger key to toggle on and off the input method, though it is easy to change the hotkey or add hotkeys with the SCIM setup configuration tool. Japanese users can now use the <code>Zenkaku_Hankaku</code> key to toggle between native and ASCII input. </para>
<section> <title>Installation</title>
<para> SCIM should be installed and run by default for Asian language desktops. Otherwise the required packages can be installed using the language support section of the package manager ( <code>pirut</code> ) or running: </para>
<screen> su -c 'yum groupinstall <language>-support' </screen>
<para> where <code><language></code> is one of <code>assamese</code> , <code>bengali</code>, <code>chinese</code>, <code>gujarati</code> , <code>hindi</code>, <code>japanese</code>, <code>kannada</code> , <code>korean</code>, <code>punjabi</code>, <code>tamil</code>, or <code>thai</code>. </para>

<screen> mkdir ~/.xinput.d ln -s /etc/X11/xinit/xinput.d/scim ~/.xinput.d/default </screen> </section>
<section> <title>SCIM applet and toolbar</title>
<para> When SCIM is running, an applet icon appears in the notification area of the desktop panel. The icon is a grey keyboard icon when SCIM is inactive, and an Input Method Engine (IME) icon when it is active. When SCIM is active, by default the SCIM input method toolbar with status information also appears. </para>
<para> Clicking the left mouse button on the applet activates a SCIM language switching menu for changing the current Input Method Engine. The menu only appears when an application using the Input Method has focus. Clicking the right mouse button on the applet or SCIM toolbar activates the setup menu. </para> </section>
<section> <title>SCIM configuration</title>
<para> You can configure SCIM and IMEs using the setup configuration tool available from the setup menu. In the IME general configuration panel, you can select which languages or IMEs appear on the language switching menu. </para> </section>

<section id="sn-Installer"> <title>Installation-Related Notes</title>
<para> This section outlines those issues that are related to <emphasis role='strong'>Anaconda</emphasis> (the Fedora Core installation program) and installing Fedora Core in general. </para>
<tip> <title>Downloading Large Files</title> <para> If you intend to download the Fedora Core DVD ISO image, keep in mind that not all file downloading tools can accommodate files larger than 2GB in size. <code>wget</code> 1.9.1-16 and above, <code>curl</code> and <code>ncftpget</code> do not have this limitation, and can successfully download files larger than 2GB. <emphasis role='strong'>BitTorrent</emphasis> is another method for downloading large files. For information about obtaining and using the torrent file, refer to <ulink url='http://torrent.fedoraproject.org/'>http://torrent.fedoraproject.org/</ulink> </para> </tip> </section>
<section> <title>Anaconda Notes</title>
<itemizedlist> <listitem> <para> <emphasis role='strong'>Anaconda</emphasis> tests the integrity of installation media by default. This function works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. The Fedora Project recommends that you test all installation media before starting the installation process, and before reporting any installation-related bugs. Many of the bugs reported are actually due to improperly-burned CDs. To use this test, type <code>linux mediacheck</code> at the <code>boot:</code> prompt. </para> <para> The <code>mediacheck</code> function is highly sensitive, and may report some usable discs as faulty. This result is often caused by disc writing software that does not include padding when creating discs from ISO files. For best results with <code>mediacheck</code> , boot with the following option: </para> <screen> linux ide=nodma </screen> <para> Use the <code>sha1sum</code> utility to verify discs before carrying out an installation. This test accurately identifies discs that are not valid or identical to the ISO image files. </para> <note> <title>BitTorrent Automatically Verifies File Integrity</title> <para> If you use <emphasis role='strong'>BitTorrent</emphasis>, any files you download are automatically validated. If your file completes downloading, you do not need to check it. Once you burn your CD, however, you should still use <code>mediacheck</code> . </para> </note> </listitem> <listitem> <para> You may perform memory testing before you install Fedora Core by entering <code>memtest86</code> at the <code>boot:</code> prompt. This option runs the <emphasis role='strong'>Memtest86</emphasis> standalone memory testing software in place of <emphasis role='strong'>Anaconda</emphasis>. <emphasis role='strong'>Memtest86</emphasis> memory testing continues until the <code>Esc</code> key is pressed. </para> <tip> <title><code>Memtest86</code> Availability</title> <para> You must boot from Installation Disc 1 or a rescue CD in order to use this feature. </para> </tip> </listitem> <listitem> <para> Fedora Core supports graphical FTP and HTTP installations. However, the installer image must either fit in RAM or appear on local storage such as Installation Disc 1. Therefore, only systems with more than 192MiB of RAM, or which boot from Installation Disc 1, can use the graphical installer. Systems with 192MiB RAM or less will fall back to using the text-based installer automatically. If you prefer to use the text-based installer, type <code>linux text</code> at the <code>boot:</code> prompt. </para> </listitem> </itemizedlist>
<section> <title>Changes in Anaconda</title>
<itemizedlist> <listitem> <para> The installer checks hardware capability and installs either the uniprocessor or SMP (Symmetric Multi Processor) kernel as appropriate in this release. Previous releases installed both variants and used the appropriate one as default. </para> </listitem> <listitem> <para> <emphasis role='strong'>Anaconda</emphasis> now supports installation on several IDE software RAID chipsets using <code>dmraid</code> . To disable this feature, add the <code>nodmraid</code> option at the <code>boot:</code> prompt. For more information, refer to <ulink url='http://fedoraproject.org/wiki/DmraidStatus'>http://fedoraproject.org/wiki/DmraidStatus</ulink> . </para> <warning> <title>Do not boot only half of a <code>dmraid</code> RAID1 (mirror)</title> <para> Various situations may occur that cause <code>dmraid</code> to break the mirror, and if you boot in read/write mode into only one of the mirrored disks, it causes the disks to fall out of sync. No symptoms arise, since the primary disk is reading and writing to itself. But if you attempt to re-establish the mirror without first synchronizing the disks, you could corrupt the data and have to reinstall from scratch without a chance for recovery. </para> <para> If the mirror is broken, you should be able to resync from within the RAID chipset BIOS or by using the <code>dd</code> command. Reinstallation is always an option. </para> </warning> </listitem> <listitem> <para> Serial mice are no longer formally supported in <emphasis role='strong'>Anaconda</emphasis> or Fedora Core. </para> </listitem> <listitem> <para> The disk partitioning screen has been reworked to be more user friendly. </para> </listitem> <listitem> <para> The package selection screen has been revamped. The new, simplified screen only displays the optional groups <emphasis>Office and Productivity</emphasis> (enabled by default), <emphasis>Software Development</emphasis>, <emphasis>Web Server</emphasis>, and <emphasis>Virtualization (Xen)</emphasis>. The <emphasis>Minimal</emphasis> and <emphasis>Everything</emphasis> shortcut groups have been removed from this screen. However, you may still fully customize your package selection. The right-click context menu provides an easy way to select all of the optional packages within a group. Refer to <ulink url='http://fedoraproject.org/wiki/Anaconda/PackageSelection'>http://fedoraproject.org/wiki/Anaconda/PackageSelection</ulink> for more details. </para> </listitem> <listitem> <para> Optional package selection has also been enhanced. In the custom package selection dialog, you can right-click any package group, and select or deselect all optional packages at one time. </para> </listitem> <listitem> <para> Firewall and SELinux configuration has been moved to the <emphasis>Setup Agent</emphasis> ( <code>firstboot</code> ), the final phase of the graphical installation process. </para> </listitem> <listitem> <para> The timezone configuration screen now features zooming areas on the location selection map. </para> </listitem> <listitem> <para> This release supports remote logging via <code>syslog</code> . To use this feature, add the option <code>syslog=host:port</code> at the boot prompt. The <code>:port</code> specifier is optional. </para> </listitem> <listitem> <para> <emphasis role='strong'>Anaconda</emphasis> now renders release notes with the <code>gtkhtml</code> widget for better capability. </para> </listitem> <listitem> <para> Kickstart has been refactored into its own package, <code>pykickstart</code> , and contains a parser and writers. As a result of this change, validation and extension is now much easier. </para> </listitem> <listitem> <para> <emphasis role='strong'>Anaconda</emphasis> now uses <code>yum</code> as the backend for solving package dependencies. Additional repositories such as Fedora Extras are expected to be supported during installation in a future release. </para> </listitem> </itemizedlist> </section>
<section> <title>Installation Related Issues</title>
<itemizedlist> <listitem> <para> Some Sony VAIO notebook systems may experience problems installing Fedora Core from CD-ROM. If this happens, restart the installation process and add the following option to the boot command line: </para> <itemizedlist> <listitem> <screen> pci=off ide1=0x180,0x386 </screen> </listitem> </itemizedlist> <para> Installation should proceed normally, and any devices not detected are configured the first time Fedora Core is booted. </para> </listitem> <listitem> <para> Not all IDE RAID controllers are supported. If your RAID controller is not yet supported by <code>dmraid</code> , you may combine drives into RAID arrays by configuring Linux software RAID. For supported controllers, configure the RAID functions in the computer BIOS. </para> </listitem> </itemizedlist> </section>
<section> <title>Upgrade Related Issues</title>
<para> Refer to <ulink url='http://fedoraproject.org/wiki/DistributionUpgrades'>http://fedoraproject.org/wiki/DistributionUpgrades</ulink> for detailed recommended procedures for upgrading Fedora. </para>
<para> In general, fresh installations are recommended over upgrades, particularly for systems which include software from third-party repositories. Third-party packages remaining from a previous installation may not work as expected on an upgraded Fedora system. If you decide to perform an upgrade anyway, the following information may be helpful. </para>
<itemizedlist> <listitem> <para> Before you upgrade, back up the system completely. In particular, preserve <code>/etc</code> , <code>/home</code> , and possibly <code>/opt</code> and <code>/usr/local</code> if customized packages are installed there. You may wish to use a multi-boot approach with a "clone" of the old installation on alternate partition(s) as a fallback. In that case, creating alternate boot media such as GRUB boot floppy. </para> <note> <title>System Configuration Backups</title> <para> Backups of configurations in <code>/etc</code> are also useful in reconstructing system settings after a fresh installation. </para> </note> </listitem> <listitem> <para> After you complete the upgrade, run the following command: </para> <itemizedlist> <listitem> <screen> rpm -qa --last > RPMS_by_Install_Time.txt </screen> </listitem> </itemizedlist> <para> Inspect the end of the output for packages that pre-date the upgrade.

<para> Refer to <ulink url='http://kernel.org/pub/linux/docs/lkml/reporting-bugs.html'>http://kernel.org/pub/linux/docs/lkml/reporting-bugs.html</ulink> for information on reporting bugs in the Linux kernel. You may also use <ulink url='http://bugzilla.redhat.com'>http://bugzilla.redhat.com</ulink> for reporting bugs which are specific to Fedora. </para> </section>
<section> <title>Following Generic Textbooks</title>
<para> Many of the tutorials, examples, and textbooks about Linux kernel development assume the kernel sources are installed under the <code>/usr/src/linux/</code> directory. If you make a symbolic link, as shown below, you should be able to use those learning materials with the Fedora Core packages. Install the appropriate kernel sources, as shown earlier, and then run the following command: </para> <screen> su -c 'ln -s /usr/src/kernels/kernel-<all-the-rest> /usr/src/linux' </screen> <para> Enter the <code>root</code> password when prompted. </para> </section>
<section> <title>Preparing for Kernel Development</title>
<para> Fedora Core does not include the kernel-source package provided by older versions since only the kernel-devel package is required now to build external modules. Configured sources are available, as described in this kernel flavors section. </para>
<note> <title>Instructions Refer to Current Kernel</title> <para> To simplify the following directions, we have assumed that you want to configure the kernel sources to match your currently-running kernel. In the steps below, the expression <version> refers to the kernel version shown by the command: <code>uname -r</code> . </para> </note>
<para> Users who require access to Fedora Core original kernel sources can find them in the kernel .src.rpm package. To create an exploded source tree from this file, perform the following steps: </para>
<caution> <title>Do Not Build Packages as Super-user (root)</title> <para> Building packages as the superuser is inherently dangerous and is not required, even for the kernel. These instructions allow you to install the kernel source as a normal user. Many general information sites refer to <code>/usr/src/linux</code> in their kernel instructions. If you use these instructions, simply substitute <code>~/rpmbuild/BUILD/kernel-<version>/linux-<version></code> . </para> </caution> <orderedlist numeration='arabic'> <listitem> <para> Prepare a RPM package building environment in your home directory. Run the following commands: </para> <screen> su -c 'yum install fedora-rpmdevtools yum-utils' fedora-buildrpmtree </screen> <para> Enter the <code>root</code> password when prompted. </para>
</listitem> <listitem> <para> Enable the appropriate <code>source</code> repository definition. In the case of the kernel released with Fedora Core 5, enable <code>core-source</code> by editing the file <code>/etc/yum.repos.d/fedora-core.repo</code>, setting the option <code>enabled=1</code>. In the case of update or testing kernels, enable the <code>source</code> definitions in <code>/etc/yum.repos.d/fedora-updates.repo</code> or <code>/etc/yum.repos.d/fedora-updates-testing.repo</code> as appropriate. </para> </listitem> <listitem> <para> Download the <code>kernel-<version>.src.rpm</code> file: </para> <screen> yumdownloader --source kernel </screen> <para> Enter the <code>root</code> password when prompted. </para> </listitem> <listitem> <para> Install <code>kernel-<version>.src.rpm</code> using the command: </para> <screen> rpm -Uvh kernel-<version>.src.rpm </screen> <para> This command writes the RPM contents into <code>${HOME}/rpmbuild/SOURCES</code> and <code>${HOME}/rpmbuild/SPECS</code>, where <code>${HOME}</code> is your home directory. </para> <tip> <title>Space Required</title> <para> The full kernel building process may require several gigabytes of extra space on the file system containing your home directory. </para> </tip> </listitem> <listitem> <para> Prepare the kernel sources using the commands: </para> <screen> cd ~/rpmbuild/SPECS rpmbuild -bp --target $(uname -m) kernel-2.6.spec </screen> <para> The kernel source tree is located in the <code>${HOME}/rpmbuild/BUILD/kernel-<version>/</code> directory. </para> </listitem> <listitem> <para> The configurations for the specific kernels shipped in Fedora Core are in the <code>configs/</code> directory. For example, the i686 SMP configuration file is named <code>configs/kernel-<version>-i686-smp.config</code> . Issue the following command to place the desired configuration file in the proper place for building: </para> <screen> cp configs/<desired-config-file> .config </screen> <para> You can also find the <code>.config</code> file that matches your current kernel configuration in the <code>/lib/modules/<version>/build/.config</code> file. </para> </listitem> <listitem> <para> Every kernel gets a name based on its version number. This is the value the <code>uname -r</code> command displays. The kernel name is defined by the first four lines of the kernel <code>Makefile</code>. The <code>Makefile</code> has been changed to generate a kernel with a <emphasis>different</emphasis> name from that of the running kernel. To be accepted by the running kernel, a module must be compiled for a kernel with the correct name. To do this, you must edit the kernel <code>Makefile</code>. </para> <para> For example, if the <code>uname -r</code> returns the string <code>2.6.15-1.1948_FC5</code> , change the <code>EXTRAVERSION</code> definition from this: </para> <screen> EXTRAVERSION = -prep </screen> <para> to this: </para> <screen> EXTRAVERSION = -1.1948_FC5 </screen> <para> That is, substitute everything from the final dash onward. </para> </listitem> <listitem> <para> Run the following command: </para> <screen> make oldconfig </screen> <para> You may then proceed as usual. </para> </listitem> </orderedlist> </section>
<section> <title>Building Only Kernel Modules</title>
<para> An exploded source tree is not required to build a kernel module, such as your own device driver, against the currently in-use kernel. Only the <code>kernel-devel</code> package is required to build external modules. If you did not select it during installation, use <emphasis role='strong'>Pirut</emphasis> to install it, going to <emphasis role='strong'>Applications > Add/Remove</emphasis> software or use <code>yum</code> to install it. Run the following command to install the <code>kernel-devel</code> package using <code>yum</code> . </para> <screen> su -c 'yum install kernel-devel' </screen> <para> For example, to build the <code>foo.ko</code> module, create the following <code>Makefile</code> in the directory containing the <code>foo.c</code> file: </para> <screen> obj-m := foo.o
KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd)
default: $(MAKE) -C $(KDIR) M=$(PWD) modules </screen> <para> Issue the <code>make</code> command to build the <code>foo.ko</code> module. </para> </section>
<section> <title>User Space Dependencies on the Kernel</title>
<para> Fedora Core has support for clustered storage through the Global File System (GFS). GFS requires special kernel modules that work in conjunction with some user-space utilities, such as management daemons. To remove such a kernel, perhaps after an update, use the <code>su -c 'yum remove kernel-<version>'</code> command instead. The <code>yum</code> command automatically removes dependent packages, if necessary. </para>

<section id="sn-Legacy"> <title>Fedora Legacy - Community Maintenance Project</title>
<para> The Fedora Legacy Project is a community-supported open source project to extend the lifecycle of select "maintenance mode" Red Hat Linux and Fedora Core distributions. The Fedora Legacy Project works with the Linux community to provide security and critical bug fix errata packages. This work extends the effective lifetime of older distributions in environments where frequent upgrades are not possible or desirable. For more information about the Fedora Legacy Project, refer to <ulink url='http://fedoraproject.org/wiki/Legacy'>http://fedoraproject.org/wiki/Legacy</ulink>. </para> <note> <title>Legacy Repo Included in Fedora Core 5</title> <para> Fedora Core 5 ships with a software repository configuration for Fedora Legacy. This is a huge step in integrating Fedora Legacy with the Fedora Project at large and Fedora Core specifically. This repository is not enabled by default in this release. </para> </note> <para> Currently the Fedora Legacy Project maintains the following distributions and releases in maintenance mode: </para>
<itemizedlist> <listitem> <para> Red Hat Linux 7.3 and 9 </para> </listitem> <listitem> <para> Fedora Core 1, 2, and 3 </para> </listitem> </itemizedlist>
<para> The Fedora Legacy Project provides updates for these releases as long as there is community interest. When interest is not sustained further, maintenance mode ends with the second test release for the third subsequent Core release. For example, maintenance mode for Fedora Core 4, if not sustained by the community, ends with the release of Fedora Core 7 test2. This provides an effective supported lifetime (Fedora Core plus Fedora Legacy Support) of about 18 months. </para>
<para> The Fedora Legacy Project always needs volunteers to perform quality assurance testing on packages waiting to be published as updates. Refer to <ulink url='http://fedoraproject.org/wiki/Legacy/QATesting'>http://fedoraproject.org/wiki/Legacy/QATesting</ulink> for more information.

<section id="sn-Multimedia"> <title>Multimedia</title>
<para> Fedora Core includes applications for assorted multimedia functions, including playback, recording and editing. Additional packages are available through the Fedora Extras repository. </para>
<section> <title>Multimedia Players</title>
<para> The default installation of Fedora Core includes <emphasis role='strong'>Rhythmbox</emphasis>, <emphasis role='strong'>Totem</emphasis>, and <emphasis role='strong'>Helix Player</emphasis> for media playback. Many other programs are available in the Fedora Core and Fedora Extras repositories, including the popular <code>XMMS</code> package. Both GNOME and KDE have a selection of players that can be used with a variety of formats. Additional programs are available from third parties to handle other formats. </para>
<para> Fedora Core also takes full advantage of the Advanced Linux Sound Architecture (ALSA) sound system. Many programs can play sound simultaneously, which was once difficult on Linux systems. When all multimedia software is configured to use ALSA for sound support, this limitation disappears. For more information about ALSA, visit the project website at <ulink url='http://www.alsa-project.org/'>http://www.alsa-project.org/</ulink>. </para> </section>
<section> <title>Ogg and Xiph.Org Foundation Formats</title>
<para> Fedora includes complete support for the Ogg media container format, and the Vorbis audio, Theora video, Speex audio, and FLAC lossless audio formats. These freely-distributable formats are not encumbered by patent or license restrictions. They provide powerful and flexible alternatives to more popular, restricted formats. The Fedora Project encourages the use of open source formats in place of restricted ones. For more information on these formats and how to use them, refer to the Xiph.Org Foundation's web site at <ulink url='http://www.xiph.org/'>http://www.xiph.org/</ulink>. </para> </section>
<section> <title>MP3, DVD and Other Excluded Multimedia</title>
<para> Fedora Core and Fedora Extras cannot include support for MP3 or DVD playback or recording, because the MP3 and MPEG (DVD) formats are patented, and the patent owners have not provided the necessary licenses. Fedora also excludes several multimedia application programs due to patent or license restrictions, such as Flash Player and Real Player. For more on this subject, please refer to <ulink url='http://fedoraproject.org/wiki/ForbiddenItems'>http://fedoraproject.org/wiki/ForbiddenItems</ulink>. </para> </section>
<section> <title>CD and DVD Authoring and Burning</title>
<para> Fedora Core and Extras include a variety of tools for easily mastering and burning CDs and DVDs. GNOME users can burn directly from the Nautilus file manager, or choose the <code>gnomebaker</code> or <code>graveman</code> packages from Fedora Extras, or the older <code>xcdroast</code> package from Fedora Core. KDE users can use the robust <code>k3b</code> package for these tasks. Console tools include <code>cdrecord</code>, <code>readcd</code>, <code>mkisofs</code>, and other typical Linux applications. </para> </section>
<section> <title>Screencasts</title>
<para> You can use Fedora to create and play back <emphasis>screencasts</emphasis>, which are recorded desktop sessions, using open technologies. Fedora Extras 5 includes <code>istanbul</code>, which creates screencasts using the Theora video format. These videos can be played back using one of several players included in Fedora Core. This is the preferred way to submit screencasts to the Fedora Project for either developer or end-user use. For a more comprehensive how-to, refer to <ulink url='http://fedoraproject.org/wiki/ScreenCasting'>http://fedoraproject.org/wiki/ScreenCasting</ulink>. </para> </section>
<section> <title>Extended Support through Plugins</title>
<para> Most of the media players in Fedora Core and Fedora Extras support the use of plugins to add support for additional media formats and sound output systems. Some use powerful backends, like <code>gstreamer</code>, to handle media format support and sound output. Plugin packages for these backends and for individual applications are available in Fedora Core and Fedora Extras, and additional plugins may be available from third parties to add even greater capabilities. </para> </section> </section> </article>

<section> <title>iproute</title>
<para> The IPv4 address deletion algorithm did not take the prefix length into account up to kernel version 2.6.12. Since this has changed, the <code>ip</code> tool from the <code>iproute</code> package now issues a warning if no prefix length is provided, to warn about possible unintended deletions: </para>
<itemizedlist> <listitem> <screen> ip addr list dev eth0 4: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 inet 10.0.0.3/24 scope global eth0 </screen> <screen> su -c 'ip addr del 10.0.0.3 dev eth0' Warning: Executing wildcard deletion to stay compatible with old scripts. Explicitly specify the prefix length (10.0.0.3/32) to avoid this warning. This special behaviour is likely to disappear in further releases, fix your scripts! </screen> </listitem> </itemizedlist>
<para> The correct method of deleting the address and thus avoiding the warning is: </para>
<screen> su -c 'ip addr del 10.0.0.3/24 dev eth0' </screen>
<para> Previously, it was not possible to tell if an interface was down administratively or because no carrier was found, such as if a cable were unplugged. The new flag <code>NO-CARRIER</code> now appears as a link flag if the link is administratively up but no carrier can be found. </para>
<para> The <code>ip</code> command now supports a batch mode via the argument <code>-batch</code>, which works similar to the <code>tc</code> command to speed up batches of tasks. </para> </section> </section>
<section> <title>Major Kernel Changes 2.6.11 - 2.6.15</title>
<para> Refer to <ulink url='http://wiki.kernelnewbies.org/LinuxChanges'>http://wiki.kernelnewbies.org/LinuxChanges</ulink> for a list of major changes. Some of them are highlighted below. </para>
<section> <title>IPv4 Address Promotion</title>
<para> Starting with version 2.6.12 of the kernel, a new feature has been added called <emphasis>named address promotion</emphasis>. This feature allows secondary IPv4 addresses to be promoted to primary addresses. Usually when the primary address is deleted, all secondary addresses are deleted as well. If you enable the new <code>sysctl</code> key <code>net.ipv4.conf.all.promote_secondaries</code>, or one of the interface specific variants, you can change this behavior to promote one of the secondary addresses to be the new primary address. </para> </section>
<section> <title>Configurable Source Address for ICMP Errors</title>
<para> By default, when selecting the source address for ICMP error messages, the kernel uses the address of the interface on which the ICMP error is going to be sent. Kernel version 2.6.12 introduces the new <code>sysctl</code> key <code>net.ipv4.icmp_errors_use_inbound_ifaddr</code>. If you enable this option the kernel uses the address of the interface that received the original error-causing packet. </para>
<para> Suppose the kernel receives a packet on interface <code>eth0</code> which generates an ICMP error, and the routing table causes the error message to be generated on interface <code>eth1</code>. If the new <code>sysctl</code> option is enabled, the ICMP error message indicates the source address as interface <code>eth0</code>, instead of the default <code>eth1</code>. This feature may ease network debugging in asynchronous routing setups. </para> </section>
<section> <title>LC-Trie Based Routing Lookup Algorithm</title>
<para> A new routing lookup algorithm called <emphasis>trie</emphasis> has been added. It is intended for large routing tables and shows a clear performance improvement over the original hash implementation, at the cost of increased memory consumption and complexity. </para> </section>
<section> <title>Pluggable Congestion Control Algorithm Infrastructure</title>
<para> TCP congestion control algorithms are now pluggable and thus modular. The legacy New<emphasis role='strong'/>Reno algorithm remains the default, and acts as the fallback algorithm. The following new congestion control algorithms have been added: </para>
<itemizedlist> <listitem> <para> High Speed TCP congestion control </para> </listitem> <listitem> <para> TCP Hybla congestion avoidance </para> </listitem> <listitem> <para> H-TCP congestion control </para> </listitem> <listitem> <para> Scalable TCP congestion control </para> </listitem> </itemizedlist>
<para> All existing congestion control modules have been converted to this new infrastructure, and the BIC congestion control has received enhancements from BICTCP 1.1 to handle low latency links. </para>
<note> <title>Affecting the Congestion Control Algorithm</title> <para> The congestion control algorithm is socket specific, and may be changed via the socket option <code>TCP_CONGESTION</code>. </para> </note> </section>
<section> <title>Queue Avoidance upon Carrier Loss</title>
<para> When a network driver notices a carrier loss, such as when the cable is pulled out, the driver stops the queue in front of the driver. In the past, this stoppage caused the packets to be queued at the queueing discipline layer for an unbound period of time causing unexpected effects. In order to prevent this effect, the core networking stack now refuses to queue any packets for a device that is operationally down, that is, has its queue disabled. </para> </section>
<section> <title>DCCP Protocol Support</title>
<para> Kernel version 2.6.14-rc1 was the first version to receive support for the DCCP protocol. The implementation is still experimental, but is known to work. Developers have begun work to make userspace applications aware of this new protocol. </para> </section>
<section> <title>Wireless</title>
<para> A new HostAP driver appears in the kernel starting in 2.6.14-rc1, which allows the emulation of a wireless access point through software. Currently this driver only works for Intersil Prism2-based cards (PC Card/PCI/PLX). Support for wireless cards Intel(R) PRO/Wireless 2100 and 2200 has been added. </para> </section>
<section> <title>Miscellaneous</title>
<itemizedlist> <listitem> <para> Many TCP Segmentation Offloading (TSO) related fixes are included. </para> </listitem> <listitem> <para> A new textsearch infrastructure has been added, and is usable with corresponding iptables and extended match. </para> </listitem> <listitem> <para> Both the IPv4 and IPv6 multicast joining interface visible by userspace have been reworked and brought up to the latest standards. </para> </listitem> <listitem> <para> The SNMPv2 MIB counter ipInAddrErrors is supported for IPv4. </para> </listitem> <listitem> <para> Various new socket options proposed in Advanced API (RFC3542) have been added. </para> </listitem> </itemizedlist> </section> </section> </section> </article>

<section> <title>System Administration</title>
<para> Improvements for administrators and developers include: </para>
<itemizedlist> <listitem> <para> The <emphasis role='strong'>Xen</emphasis> virtualization system has enhanced support. The tools to configure <emphasis role='strong'>Xen</emphasis> virtual machines on your Fedora Core system now use the standard graphical installation process, run as a window on your desktop. Fedora developers have also created <code>gnome-applet-vm</code>, which provides a simple virtual domains monitor applet, and <code>libvirt</code> (<ulink url='http://libvirt.org/'>http://libvirt.org/</ulink>), a library providing an API to use Xen virtualization capabilities. </para> </listitem> <listitem> <para> The industry-leading <code>anaconda</code> installation system continues to evolve. New features for this release include remote logging and improved support for tracebacks. Package management in the installation system is now provided by <code>yum</code>. This enhancement is the first step in enabling access to Fedora Extras from within the installation process. </para> </listitem> <listitem> <para> Version 2.2 of the <emphasis role='strong'>Apache</emphasis> HTTP server is now included. This release provides enhancements to authentication, database support, proxy facilities, and content filtering. </para> </listitem> <listitem> <para> The latest generation of database servers are packaged in this release, including both <emphasis role='strong'>MySQL</emphasis> 5.0 and <emphasis role='strong'>PostgreSQL</emphasis> 8.1. </para> </listitem> <listitem> <para> Several native Java programs are now available compiled with <code>GCJ</code>, such as the <emphasis role='strong'>Geronimo</emphasis> J2EE server and the <emphasis role='strong'>Apache Jakarta</emphasis> Project, in addition to the Java programs and development capabilities in the previous releases. </para> </listitem> <listitem> <para> There are new tools for system monitoring and performance analysis. This release includes <emphasis role='strong'>SystemTap</emphasis> (<ulink url='http://fedoraproject.org/wiki/SystemTap'>http://fedoraproject.org/wiki/SystemTap</ulink>), an instrumentation system for debugging and analyzing performance bottle necks, and <emphasis role='strong'>Frysk</emphasis> (<ulink url='http://fedoraproject.org/wiki/Frysk'>http://fedoraproject.org/wiki/Frysk</ulink>), an execution analysis technology for monitoring running processes or threads which are provided as technology previews in this release. </para> </listitem> <listitem> <para> This release includes <code>system-config-cluster</code>, a utility that allows you to manage cluster configuration in a graphical setting. </para> </listitem> <listitem> <para> The combination of <emphasis role='strong'>Kexec</emphasis> and <emphasis role='strong'>Kdump</emphasis> (<ulink url='http://lse.sourceforge.net/kdump/'>http://lse.sourceforge.net/kdump/</ulink>) utilities provides modern crash dumping facilities and potential for faster bootup, bypassing the firmware on reboots. <emphasis role='strong'>Kexec</emphasis> loads a new kernel from a running kernel, and <emphasis role='strong'>Kdump</emphasis> can provide a memory dump of the previous kernel for debugging. </para> </listitem> <listitem> <para> This release includes <code>iscsi-initiator-utils</code>, iSCSI daemon and utility programs that provide support for hardware using the iSCSI interface. </para> </listitem> <listitem> <para> <code>fedora-release</code> now includes the software repositories for debuginfo packages and source <code>rpm</code> packages. </para> </listitem> <listitem> <para> <code>fedora-release</code> now includes the software repositories for Fedora Legacy community maintenance project. (disabled by default) </para> </listitem> </itemizedlist> </section>
<section> <title>System Level Changes</title>
<itemizedlist> <listitem> <para> X.org X11R7.0 is included in this release. The new modular architecture of R7.0 enables easier driver upgrades and simplifies development, opening the way for rapid improvement in Linux graphics. </para> </listitem> <listitem> <para> The GCC 4.1 compiler (<ulink url='http://gcc.gnu.org/gcc-4.1/changes.html'>http://gcc.gnu.org/gcc-4.1/changes.html</ulink>) is included, and the entire set of Fedora packages is built with this technology. This provides security and performance enhancements throughout the system. </para> </listitem> <listitem> <para> The kernels for this release are based on Linux 2.6.16. Refer to the section on the kernel in these release notes for other details. </para> </listitem> <listitem> <para> The PCMCIA framework used by laptop and mobile devices has changed. The older <code>pcmcia-cs</code> package using the <code>cardmgr/pcmcia</code> service has been replaced with a new <code>pcmciautils</code> package. With <code>pcmciautils</code>, PCMCIA devices are handled directly and dynamically by the <code>hotplug</code> and <code>udev</code> subsystems. This update increases both efficiency and performance of the system. For more information about these changes, refer to <ulink url='http://www.kernel.org/pub/linux/utils/kernel/pcmcia/pcmcia.html'>http://www.kernel.org/pub/linux/utils/kernel/pcmcia/pcmcia.html</ulink>. </para> </listitem> <listitem> <para> SELinux implementation has undergone a major change, with a switch to the SELinux reference policy (<ulink url='http://serefpolicy.sourceforge.net/'>http://serefpolicy.sourceforge.net/</ulink>). The SELinux reference policy can support binary policy modules. It is now possible to move SELinux policies into individual packages, making it easier for users to ship site-specific policy customizations when required. This version also adds support for Multi-Category Security (MCS), enabled by default, and Multi-Level Security (MLS). SELinux continues to offer support for TE (Type Enforcement), enabled by default, and RBAC (Role-Based Access Control). Refer to the section on SELinux in these release notes for other details and links to SELinux resources on the Fedora Project pages. </para> </listitem> </itemizedlist> <anchor id='udev'/> <para></para>
<itemizedlist> <listitem> <para> <code>udev</code> provides a new linking for device names that includes the physical name of the device. For example, if your CD-ROM is <code>/dev/hdc</code>, it gets symlinked to the friendly name <code>/dev/cdrom-hdc</code>. If you have additional matching devices, the same rule applies, so <code>/dev/hdd</code> is symlinked to <code>/dev/cdrom-hdd</code>. This is true for <code>/dev/scanner</code>, <code>/dev/floppy</code>, <code>/dev/changer</code>, and so forth. </para> <para> The typical name <code>/dev/cdrom</code> is also created, and <code>udev</code> assigns it randomly to one of the <code>/dev/cdrom-hdX</code> devices. This random assignment usually sticks, but in some configurations the symlink may change on boot to a different device. This does not affect CD burning applications, but some CD player applications such as <code>kscd</code> may be affected. If you wish, you can set your CD player application to point at a specific CD-ROM device, such as <code>/dev/cdrom-hdc</code>. This situation only occurs if you have more than one of a type of device. </para> </listitem> </itemizedlist> </section> </section>

<section id="sn-PackageNotes"> <title>Package Notes</title>
<para> The following sections contain information regarding software packages that have undergone significant changes for Fedora Core . For easier access, they are generally organized using the same groups that are shown in the installation system. </para>
<section> <title>Core utilities POSIX changes</title>
<para> The <code>coreutils</code> package now follows the POSIX standard version 200112. This change in behavior might affect scripts and command arguments that were previously deprecated. For example, if you have a newer system but are running software that assumes an older version of POSIX and uses <code>sort +1</code> or <code>tail +10</code>, you can work around any compatibility problems by setting <code>_POSIX2_VERSION=199209</code> in your environment. Refer to the section on standards in the <code>coreutils</code> info manual for more information on this. You can run the following command to read this information. </para>
<screen> info coreutils Standards </screen> </section>
<section> <title>Pango Text Renderer for Firefox</title>
<para> Fedora is building Firefox with the Pango system as the text renderer. This provides better support for certain language scripts, such as Indic and some CJK scripts. Pango is included with with permission of the Mozilla Corporation. This change is known to break rendering of MathML, and may negatively impact performance on some pages. To disable the use of Pango, set your environment before launching Firefox: </para>
<screen> MOZ_DISABLE_PANGO=1 /usr/bin/firefox </screen> <para> Alternately, you can include this environment variable as part of a wrapper script. </para> </section>
<section> <title>Smbfs deprecated</title>
<para> The kernel implementation of <emphasis role='strong'>smbfs</emphasis> to support the Windows file sharing protocol has been deprecated in favor of <emphasis role='strong'>cifs</emphasis>, which is backwards compatible with <emphasis role='strong'>smbfs</emphasis> in features and maintenance. It is recommended that you use the <emphasis role='strong'>cifs</emphasis> filesystem in place of <emphasis role='strong'>smbfs</emphasis>. </para> </section>
<section> <title>Yum kernel handling plugin</title>
<para> A <code>yum</code> plugin written by Red Hat developers is provided by default within the yum package which only retains the latest two kernels in addition to the one being installed when you perform updates on your system. This feature can be fine tuned to retain more or less kernels or disabled entirely through the <code>/etc/yum/pluginconf.d/installonlyn.conf</code> file. There are other plugins and utilities available as part of <code>yum-utils</code> package in Fedora Extras software repository. You can install them using the following command. </para>
<screen> yum install yum-utils </screen> </section>
<section> <title>Yum cache handling behavior changes</title>
<para> By default, <code>yum</code> is now configured to remove headers and packages downloaded after a successful install to reduce the ongoing disk space requirements of updating a Fedora system. Most users have little or no need for the packages once they have been installed on the system. For cases where you wish to preserve the headers and packages (for example, if you share your <code>/var/cache/yum</code> directory between multiple machines), modify the keepcache option to <code>1</code> in <code>/etc/yum.conf</code>. </para> </section>
<section> <title>Kernel device, module loading, and hotplug changes</title>
<para> The hotplug and device handling subsystem has undergone significant changes in Fedora Core. The <code>udev</code> method now handles all module loading, both on system boot and for hotplugged devices. The <code>hotplug</code> package has been removed, as it is no longer needed. </para>
<para> Support for hotplug helpers via the <code>/etc/hotplug</code>, <code>/etc/hotplug.d</code>, and <code>/etc/dev.d</code> directories is deprecated, and may be removed in a future Fedora Core release. These helpers should be converted to <code>udev</code> rules. Please see <ulink url='http://www.reactivated.net/writing_udev_rules.html'>http://www.reactivated.net/writing_udev_rules.html</ulink> for examples. </para> </section>
<section> <title>Systemwide Search Changes</title>
<note> <title role="strong"><code>mlocate</code> Has Replaced <code>slocate</code></title> <para> The new <code>mlocate</code> package provides the implementations of <code>/usr/bin/locate</code> and <code>/usr/bin/updatedb</code>. Previous Fedora releases included the <code>slocate</code> versions of these programs. </para> </note> <itemizedlist> <listitem> <para> The <code>locate</code> command should be completely compatible. </para> </listitem> <listitem> <para> The configuration file <code>/etc/updatedb.conf</code> is compatible. </para> </listitem> <listitem> <para> Syntax errors that <code>slocate</code> would not detect are now reported. </para> </listitem> <listitem> <para> The <code>DAILY_UPDATE</code> variable is not supported. </para> </listitem> <listitem> <para> The <code>updatedb</code> command is <emphasis>not</emphasis> compatible, and custom scripts that use <code>updatedb</code> may have to be updated. </para> </listitem> </itemizedlist> </section>
<section> <title>Mouse Configuration Utility Removed</title>
<para> The <code>system-config-mouse</code> configuration utility has been dropped in this release because <code>synaptic</code> and three-button mouse configuration is handled automatically. Serial mice are no longer supported. </para> </section>
<section> <title>Up2date and RHN applet are removed</title>
<para> The <code>up2date</code> and <code>rhn-applet</code> packages have been removed from Fedora Core 5. Users are encouraged to use the <code>yum</code> tool from the command line, and the <emphasis role='strong'>Pirut</emphasis> software manager and <emphasis role='strong'>Pup</emphasis> update tool from the desktop. </para> </section>
<section> <title>NetworkManager</title>
<para> Fedora systems use <code>Network</code> <code>Manager</code> to automatically detect, select, and configure wired and wireless network connections. Wireless network devices may require third-party software or manual configuration to activate after the installation process completes. For this reason, Fedora Core provides <code>Network</code> <code>Manager</code> as an optional component. </para>
<para> Refer to <ulink url='http://fedoraproject.org/wiki/Tools/NetworkManager'>http://fedoraproject.org/wiki/Tools/NetworkManager</ulink> for more information on how to install and enable <code>Network Manager</code>. </para> </section>
<section> <title>Dovecot</title>
<para> Fedora Core includes a new version of the <code>dovecot</code> IMAP server software, which has many changes in its configuration file. These changes are of particular importance to users upgrading from a previous release. Refer to <ulink url='http://wiki.dovecot.org/UpgradingDovecot'>http://wiki.dovecot.org/UpgradingDovecot</ulink> for more information on the changes. </para> </section>
<section> <title>Kudzu</title>
<para> The <code>kudzu</code> utility, <code>libkudzu</code> library, and <code>/etc/sysconfig/hwconf</code> hardware listing are all deprecated, and will be removed in a future release of Fedora Core. Applications which need to probe for available hardware should be ported to use the HAL library. More information on HAL is available at <ulink url='http://freedesktop.org/wiki/Software/hal'>http://freedesktop.org/wiki/Software/hal</ulink>. </para> </section>
<section> <title>No automatic fstab editing for removable media</title>
<para> The <code>fstab-sync</code> facility has been removed. In Fedora Core , the <code>fstab-sync</code> program is removed in favor of desktop specific solutions for mounting removable media. Entries for hotplug devices or inserted media are no longer automatically added to the <code>/etc/fstab</code> file. Command-line users may migrate to <code>gnome-mount</code>, which provides similar functionality. </para> </section>
<section> <title>Mounting of Fixed Disks in Gnome and KDE</title>
<para> As part of the changes to the mounting infrastructure, the desktop's automatic mountable devices detection now includes policy definitions that ignore all fixed disk devices from. This was done to increase security on multi-user systems. People on multi-user systems who want to make changes to disk mounting that could impact the multi-user environment are advised to understand the implications of the default HAL policy decisions and to review the HAL policy files in <code>/usr/share/hal/fdi/policy/</code>. </para>
<para> If you are on a single-user system and would like to recover the functionality to mount fixed disk items such as IDE partitions from the desktop, you can modify the default HAL policy. To enable deskop mounting for all fixed disks: </para>
<screen> su -c 'mv /usr/share/hal/fdi/policy/10osvendor/99-redhat-storage-policy-\ fixed-drives.fdi /root/' su -c '/sbin/service haldaemon restart' </screen> <para> If you need more fine-grained control and only want to expose certain fixed disks for desktop mounting, read over how to create additional HAL policy to selectively ignore/allow fixed disk devices. </para> </section>
<section> <title>GnuCash</title>
<para> The PostgreSQL backend for <emphasis role='strong'>GnuCash</emphasis> has been removed, as it is unmaintained upstream, does not support the full set of <emphasis role='strong'>GnuCash</emphasis> features, and can lead to crashes. Users who use the PostgreSQL backend should load their data and save it as an XML file <emphasis role='strong'>before</emphasis> upgrading <emphasis role='strong'>GnuCash</emphasis>. </para> </section>
<section> <title>Mozilla</title>
<para> The <emphasis role='strong'>Mozilla</emphasis> application suite is deprecated. It is shipped in Fedora Core and applications can expect to build against <code>mozilla-devel</code>, however it will be removed in a future release of Fedora Core. </para> </section>
<section> <title>Booting without initrd</title>
<para> Booting Fedora Core without the use of an initrd is deprecated. Support for booting the system without an initrd may be removed in future releases of Fedora Core. </para> </section>
<section> <title>libstc++ preview</title>
<para> The <code>libstdc++so7</code> package has been added. This package contains a preview of the GNU Standard C++ Library from <code>libstdcxx_so_7-branch</code>. It is considered experimental and unsupported. Do not build any production software against it, as its ABI and so-version will change in future upgrades. To build software using this library, invoke <code>g++-libstdc++so_7</code> instead of <code>g++</code>. </para> </section>
<section> <title>LinuxThreads support removed</title>
<para> The LinuxThreads library is no longer available. LinuxThreads was deprecated in Fedora Core 4 and is no longer available in this release. The Native POSIX Threading Library (NPTL), which has been the default threading library since Red Hat Linux 9, has replaced LinuxThreads completely. </para> </section> </section> </article>

<section id="sn-ProjectOverview"> <title>About the Fedora Project</title>
<para> The goal of the Fedora Project is to work with the Linux community to build a complete, general-purpose operating system exclusively from open source software. Development is done in a public forum. The project produces time-based releases of Fedora Core approximately 2-3 times a year, with a public release schedule available at <ulink url='http://fedora.redhat.com/About/schedule/'>http://fedora.redhat.com/About/schedule/</ulink>. The Red Hat engineering team continues to participate in building Fedora Core and invites and encourages more outside participation than was possible in the past. By using this more open process, we hope to provide an operating system more in line with the ideals of free software and more appealing to the open source community. </para>

<section> <title>PAM module Deprecation</title>
<para> <code>Pam_stack</code> is deprecated in this release. Linux-PAM 0.78 and later contains the <code>include</code> directive which obsoletes the <code>pam_stack</code> module. <code>pam_stack</code> module usage is logged with a deprecation warning. It might be removed in a future release. It must not be used in individual service configurations anymore. All packages in Fedora Core using PAM were modified so they do not use it. </para>
<tip> <title>Upgrading and PAM Stacks</title> <para> When a system is upgraded from previous Fedora Core releases and the system admininstrator previously modified some service configurations, those modified configuration files are <emphasis>not</emphasis> replaced when new packages are installed. Instead, the new configuration files are created as <code>.rpmnew</code> files. Such service configurations must be fixed so the <code>pam_stack</code> module is not used. Refer to the <code>.rpmnew</code> files for the actual changes needed. </para> <screen> diff -u /etc/pam.d/foo /etc/pam.d/foo.rpmnew </screen> </tip>

<section> <title>Buffer Overflow detection and variable reordering</title>
<para> All of the software in Fedora Core and Extras software repository for this release is compiled using a security feature called a <emphasis>stack protector</emphasis>. This was using the compiler option <code>-fstack-protector</code>, which places a canary value on the stack of functions containing a local character array. Before returning from a protected function, the canary value is verified. If there was a buffer overflow, the canary will no longer match the expected value, aborting the program. The canary value is random each time the application is started, making remote exploitation very difficult. The stack protector feature does not protect against heap-based buffer overflows. </para>
<para> This is a security feature written by Red Hat developers (<ulink url='http://gcc.gnu.org/ml/gcc-patches/2005-05/msg01193.html'>http://gcc.gnu.org/ml/gcc-patches/2005-05/msg01193.html</ulink>), reimplementing the IBM ProPolice/SSP feature.

<section id="sn-Xorg"> <title>X Window System (Graphics)</title>
<para> This section contains information related to the X Window System implementation provided with Fedora. </para>
<section> <title>xorg-x11</title>
<para> X.org X11 is an open source implementation of the X Window System. It provides the basic low-level functionality upon which full-fledged graphical user interfaces (GUIs) such as GNOME and KDE are designed. For more information about X.org, refer to <ulink url='http://xorg.freedesktop.org/wiki/'>http://xorg.freedesktop.org/wiki/</ulink>. </para>
<para> You may use <emphasis>System > Administration > Display</emphasis> or <emphasis role='strong'>system-config-display</emphasis> to configure the settings. The configuration file for X.org is located in <code>/etc/X11/xorg.conf</code>. </para>
<para> X.org X11R7 is the first modular release of X.org, which, among several other benefits, promotes faster updates and helps programmers rapidly develop and release specific components. More information on the current status of the X.org modularization effort in Fedora is available at <ulink url='http://fedoraproject.org/wiki/Xorg/Modularization'>http://fedoraproject.org/wiki/Xorg/Modularization</ulink>. </para> </section>

<section> <title>X.org X11R7 Developer Overview</title>
<para> The following list includes some of the more visible changes for developers in X11R7: </para>
<itemizedlist> <listitem> <para> The entire buildsystem has changed from <code>imake</code> to the GNU <code>autotools</code> collection. </para> </listitem> <listitem> <para> Libraries now install <code>pkgconfig</code> <code>*.pc</code> files, which should now always be used by software that depends on these libraries, instead of hard coding paths to them in <code>/usr/X11R6/lib </code> or elsewhere. </para> </listitem> <listitem> <para> Everything is now installed directly into <code>/usr</code> instead of <code>/usr/X11R6</code>. All software that hard codes paths to anything in <code>/usr/X11R6</code> must now be changed, preferably to dynamically detect the proper location of the object. Developers are <emphasis role='strong'>strongly</emphasis> advised against hard-coding the new X11R7 default paths. </para> </listitem> <listitem> <para> Every library has its own private source RPM package, which creates a runtime binary subpackage and a <code>-devel</code> subpackage. </para> </listitem> </itemizedlist> </section>
<section> <title>X.org X11R7 Developer Notes</title>
<para> This section includes a summary of issues of note for developers and packagers, and suggestions on how to fix them where possible. </para>
<section> <title>The /usr/X11R6/ Directory Hierarchy</title>
<para> X11R7 files install into <code>/usr</code> directly now, and no longer use the <code>/usr/X11R6/</code> hierarchy. Applications that rely on files being present at fixed paths under <code>/usr/X11R6/</code>, either at compile time or run time, must be updated. They should now use the system <code>PATH</code>, or some other mechanism to dynamically determine where the files reside, or alternatively to hard code the new locations, possibly with fallbacks. </para> </section>
<section> <title>Imake</title>
<para> The <code>imake</code> xutility is no longer used to build the X Window System, and is now officially deprecated. X11R7 includes <code>imake</code>, <code>xmkmf</code>, and other build utilities previously supplied by the X Window System. X.Org highly recommends, however, that people migrate from <code>imake</code> to use GNU <code>autotools</code> and <code>pkg-config</code>. Support for <code>imake</code> may be removed in a future X Window System release, so developers are <emphasis role='strong'>strongly</emphasis> encouraged to transition away from it, and not use it for any new software projects. </para> </section>
<section> <title>The Systemwide app-defaults/ Directory</title>
<para> The system <code>app-defaults/</code> directory for X resources is now <code>%{_datadir}/X11/app-defaults</code>, which expands to <code>/usr/share/X11/app-defaults/</code> on Fedora Core and for future Red Hat Enterprise Linux systems. </para> </section>
<section> <title>Correct Package Dependencies</title>
<para> Any software package that previously used <code>Build Requires: (XFree86-devel|xorg-x11-devel)</code> to satisfy build dependencies must now individually list each library dependency. The preferred and recommended method is to use <emphasis>virtual</emphasis> build dependencies instead of hard coding the library package names of the <code>xorg</code> implementation. This means you should use <code>Build Requires: libXft-devel</code> instead of <code>Build Requires: xorg-x11-Xft-devel</code>. If your software truly does depend on the X.Org X11 implementation of a specific library, and there is no other clean or safe way to state the dependency, then use the <code>xorg-x11-devel</code> form. If you use the virtual provides/requires mechanism, you will avoid inconvenience if the libraries move to another location in the future. </para> </section>
<section> <title>xft-config</title>
<para> Modular X now uses GNU <code>autotools</code> and <code>pkg-config</code> for its buildsystem configuration and execution. The <code>xft-config</code> utility has been deprecated for some time, and <code>pkgconfig</code> <code>*.pc</code> files have been provided for most of this time. Applications that previously used <code>xft-config</code> to obtain the <code>Cflags</code> or <code>libs</code> build options must now be updated to use <code>pkg-config</code>. </para> </section> </section> </section> </article>
