Boot speedup with readahead

[Harald Hoyer <harald redhat com>]

Hello fellow Fedora developers,

recently readahead was modified to adapt to system file changes and to start very early in the boot process 
via upstart.

I would like to encourage you to test readahead-1.4.5-3.fc10 from rawhide (even possible on F9), which I built 
some minutes ago. It may take a day to reach your local mirror.

# yum --enablerepo=rawhide install readahead
or
# yum --enablerepo=rawhide update readahead

With the next reboot readahead-collector runs and collects the information which files are used during the 
boot process. The next reboot then, readahead read ahead those files and the boot process (from init start to 
gdm login screen) should be approx. 10% faster.

Hope it speeds up your boot process a little bit. Please report any changes in your boot time (can be measured 
with a stop clock or bootchart).

You can modify /etc/sysconfig/readahead to turn readahead on/off.
