i was going to suggest building an RPM which installs a script in 
/etc/init.d and enables it in rc1.d-rc3.d, this script checks to see if 
its run before, and if not, it runs, does its thing, then sets some kind 
of marker saying "been there, done that", and disables itself with 
`chkconfig servicename off`

this way the script could be run early in the init sequence (by using a 
low S?? in the symlink) or late, as you so need.
