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.

Glad to see that!  Sorry I helped put the hammer down on older readahead
in the F8 era... but it was pretty broken back then ... ;)

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.

So when / how often does readahead-collector run now?

Thanks,
-Eric
