 I'm not sure if we need to run the daemon for every boot. I don't
 know how expensive is our audit system... we will see.

 Prepare a new version of the readahead.d/default.later file  is
 very simple (one qsort) and I think it will be possible to do it
 automatically. So, without a separate command.

 More attractive is to generate final version of the lists where
 filenames are sorted by first data block -- see "fast mode" in
 https://hosted.fedoraproject.org/projects/readahead/browser/README.

 Now in FC6 readahead supports the "full mode" only. The readahead in
 FC7 will support both modes, but regenerate lists for  "fast mode" is
 more expensive -- it seems like a good job for cron or some manually
 started command.

 Yeah, that's always more clear than my mails. Sorry ;-)
