Versions after the rpi-update script
The best part of the
rpi-update
script is that it will keep you up to date daily with the foundation's GitHub
repository, unlike your distribution's repository, which may lag a little.
Lastly, for your handy reference I have included a full kernel module listing with this command:
# lsmod
If you're having issues with any of the hardware projects, check Figure
2-13
to ensure that you have all the correct
modules loaded.

Kernel module listing for the Raspberry Pi
Now your Fedora installation is current. It's now time to strip out the fat and configure the Raspberry Pi.
Cutting Out the Fat
Why do you need to optimize Fedora, I hear you say, it's already running quite well? Out of the box, Fedora runs quite
well; the Raspberry Pi remix has done really well to have such a low memory footprint. Still, even with this excellent
out-of-the-box install, there are a few simple tweaks that will make the Fedora remix on the Raspberry Pi work better
under a high load. In addition to just saving CPU cycles the other parts of the Raspberry Pi will benefit too.
Optimizing the SD Card
An SD card behaves very differently than a standard hard disk drive. SD cards have a limit on the number of
write-and-erase cycles that they can perform, unlike a traditional hard disk drive where there is no concept of a
write-and-erase cycle.
