I might add here that I have done the same thing for Tomcat and JBoss servers 
on SuSE distros. What I have found that works for me is to copy the Apache 
startup script and hack it to my needs. The scripts on SuSE check a 
configuration variable to decide whether to start the service or not, then 
check for the existence of the service, and that dependent services have 
already been started, such as the network. I imagine that RedHat does 
something similar in most respects.
