Should a livecd be created ext3 or ext4.
The reason I ask, is we tend offer the livecd's also as usb sticks, when I last tried the usb stick does not boot if the filesystem is ext4.
Comments anyone?
Fedora 11 Live CD's will use Ext4 by default but retain a small /boot partition formatted as Ext3. Since GRUB doesn't support LVM and Fedora uses LVM by default, a separate /boot is needed anyway. You can create a customized live cd with a different filesystem by using --fstype in kickstart.
This isn't entirely accurate. The live images themselves are entirely ext4. When you install them on a hard drive, we make an ext3 /boot and do some shuffling in anaconda.
The ext4 live image is compressed inside of a squashfs which is then placed on your USB stick which should be formatted either as vfat, ext2, or ext3. I don't believe that extlinux (which we use for booting ext* USB sticks with live images on them) supports ext4 yet
