Unfortunately you're right. I'm really thinking that we need to
complete remove this package from Fedora 9.
Shouldn't we then disable it for F8? AFAIK we also wanted to
remove
many other less critical services that are only needed on a low
percentage of installed systems.
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>"
