Description Benjamin Delfin 2002-11-04 12:43:07 EST

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461)

Description of problem:
rc launches all kill and start scripts in /etc/rc.d/rc*.d one-at-a-time, 
waiting for each to finish.  By starting up all kill or start scripts with the 
same number (eg. 17 for S17xinetd) in the background, then waiting for all of 
them to finish, startup time can be cut.  There's no reason not to launch non-
network services while waiting for a network service to come up.  Careful 
tweaking to see which packages can be started in parallel will allow for 
significantly lower bootup times.

A better solution would be to take actual dependencies into account; we'll
probably look towards doing something in that way in the future.
