chkconfig is a command line tool where you can specify what services you
want started at boot time.  

chkconfig --list

spits out a nice chart of what apps get started at the different
run-levels at boottime

You can also define what run-levels you want each prog to start under.  
example:

chkconfig --level 345 mysql on

tells the init script to run the mysql script in /etc/rc.d/init.d when
ever linux enter run level 3,4, or 5

I'd much rather use chkconfig to set run-level startups than to just
have it start all the time.  No need to start up some apps when booting
into single user mode(run level 1, you know how to do that, right? :) )
