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,
