There's probably more that can be removed. Many of the
fedora-*.services can be removed depending on your system
configuration. For instance, I removed the fedora-readonly.service
since I don't use read-only /. If you don't use LVM, RAID, or
Multipath, you can speed up your boot significantly.
The author of systemd explained a lot of this in detail here:

F16 kde plasma crashes - occasional
by mike cloaked
I have been running f16 x86_64 with kde 4.7.3 for a week or two on two
different machines. Occasionally I have found that the screen saver
kicks in but then fails to time out and so the screensaver runs
continuously without powersaving the monitor after a period as
normally happens. Occasionally I have had chrome not close down
properly and leaves a tab in the panel labeled as chrome but not able
to remove it except that moving to a different desktop with a keyboard
switch sometimes mysteriously fixes it. So there appears to be some
mysterious instability in kde 4.7.3 that I can't easily diagnose.
There is nothing I can find in the logs to indicate a problem but it
is a little irritating - I can't roll out kde on f16 to less
experienced users until kde becomes really stable. These issues are
happening several times per day for a machine that is in use (by me).
Once a machine is left to its own devices with the screensaver running
and once it has gone into monitor powersave it seems stable - but it
doesn't always get to that stage, and these randomly timed
instabilities are an annoyance. Anyone else had any similar issues?
I have seen on a gentoo list that people are also seeing instability
with 4.7.3 and are making comments that kde 4.8 looks much more
stable! Does anyone know what is the status is of kde development
with regard to Fedora and the rollout timescale for kde 4.8?
Thanks

systemd-analyze blame and missing swap?
by Tom Horsley
I just had a disk go bad on me, and after unplugging it
and restoring the backup to another mostly empty disk,
boots were taking forever.
So, since systemd-analyze blame had just showed up
in another thread, I thought I would try it and see
what it showed, but the longest time it has is
2294ms for network.service, and the pause I was
seeing was more like 40 seconds than 3 seconds.
I finally looked at boot.log and saw the error message
that scrolled past too fast about the swap partition
which I had forgotten was on that dead disk.
So why doesn't systemd-analyze blame show the
giant timeout for attempting to start swap?
Is there some other analyze parameter that does that?

Re: Can't install nvidia drivers on Laptop

You refer to kmod's and akmod version drivers. Have you tried building
your own from the bin file?
Add rdblacklist=nouveau to the kernel line in your grub conf file
Change 'inittab' to boot to multi-user (what was level 3);
rm -vf /etc/systemd/system/default.target
ln -s /lib/systemd/system/multi-user.target
/etc/systemd/system/default.target
(that is all one line)
Download the NVIDIA.....bin file and chmod it to 755
Reboot, login, cd to where the NVIDIA file is and launch it.
It will compile the driver against your running kernel.

Need help to fix ruby, rails,rvm
by Roger
I installed ruby, rails, gem, rvm in ubuntu 11.10 and tried to update
ruby from 1.8.7 to the recommended 1.9.2 and it fails.
No matter what I do rails reports /usr/bin/ruby1.8: bad interpreter:
ls -l /usr/bin/ruby*
lrwxrwxrwx 1 root root 22 2011-11-24 14:02 /usr/bin/ruby ->
/etc/alternatives/ruby
-rwxr-xr-x 1 root root 5516 2011-07-28 07:24 /usr/bin/ruby1.9.1
ls -l /usr/bin/gem*
lrwxrwxrwx 1 root root 21 2011-11-24 14:02 /usr/bin/gem ->
/etc/alternatives/gem
-rwxr-xr-x 1 root root 545 2011-05-17 06:47 /usr/bin/gem1.8
-rwxr-xr-x 1 root root 547 2011-07-28 06:10 /usr/bin/gem1.9.1
lrwxrwxrwx 1 root root 8 2011-04-11 03:45 /usr/bin/gemtopbm -> gemtopnm
-rwxr-xr-x 1 root root 9572 2010-06-25 22:50 /usr/bin/gemtopnm
Synaptic says that 1.9.1 is 1.9.2 and this is confusing because 1.9.1
has incompatibilities.
I have tried erasing and deleting all instances of ruby, rails, rvm and
reinstalling with apt-get, with rvm, etc but am so stuck.
Googling has not helped, Ive been at it all day and no luck, how should
this be solved please?
Many thanks in advance

Firefox Issues Resolved
by Fedora User
I was having problems is FF 8.0-03 causing 100% usage spikes. Removing
all of the extensions and add-ons had no effect. Nor did deleting
the .mozilla directory.
HOWEVER, FF 8.01 from source works perfectly and eliminates the problem
completely.

Is android linux done right?
by Skunk Worx
Android may be the fastest growing linux distribution in history.
Now that Google has open sourced Ice Cream Sandwich, will some linux
distribution leverage the Android "Java Desktop" just as Android
leveraged the linux kernel?
Is the Android WM / Compositor so different from X11 that it is simply
unpossible?
Could an ICS port to X86 use bits of the open source nouveau or radeon
drivers and thus become a fairly decent decent desktop or laptop OS,
maybe even to the point of accessing the various app stores?
Could this be a future version of Fedora?

Two instances of Inbox, one as subfolder
by Jonathan Ryshpan
I suddenly have two instances of my Inbox folder, one at the top level
and the other as a subfolder of Drafts. The one at the top level
appears to have everything that the one in Drafts does plus more mail
that has come in since 9:00am today. A screenshot is attached.
Any ideas about what happened? I think most likely I accidentally
dragged Inbox into Drafts (I have a slight tremor). Is there any harm
in deleting Inbox/Drafts?
Thanks - jon
