I add stuff like oracle startup commands, my sound driver extras, a 
netrek server, qmail and a few other things to rc.local.

 It's my understanding that rc.local should be run every time the machine 
books, after everything else.

 If the default runlevel is 3, and someone does "init 5", rc.local is re-
run, and chaos ensues. A simple fix for this would be to add

        touch /var/lock/subsys/local

 to /etc/rc.local and to add 

        rm -f /var/lock/subsys/local 

to rc.sysinit. Pretty please ?
