 Unfortunately you're right. I'm really thinking that we need to
 complete remove this package from Fedora 9.

 I agree that readahead_{easy,later} should be disabled by default.

 I'd like to test it on an old HW (for example a laptop with slow HDD)
 and see more bootcharts.

 Volunteers? ...

 # chkconfig readahead_early on
 # chkconfig readahead_later on
 # yum install bootchart
 # reboot
  ...
 # mutt -a /var/log/bootchart.tgz -s "bootchart: <hw description>" kzak redhat com

 (For more details: http://www.bootchart.org/.)
