It's a gain for those really long startup daemons. Maybe xfs has to
recache its fonts, or maybe ntpdate is syncing with the time server.
Then again, if Apache were written in a Bash script with all of its
functions in separate script files and configuration spread out in
different files and sourced in, parallelism would be an issue wouldn't
it?
I actually retooled this: http://www.fefe.de/minit/ for Redhat once and
the results were just night and day. Of course, I didn't run kudzu or
anything complicated like that. Just brought up the stuff I needed.
You practically don't even need hibernate or sleep when you get it this
good. (Doesn't help with X/GNOME/KDE startup, though) ;-)
have fun,
