Notice that the install-oacs script has a section of settings, where one can define the install-dir, user/group names, db-name etc. So it is probably easier to change these settings than to fiddle around afterwards.
Maybe we should provide command line switches to ease adaptation, but having a common set of parameters helps communication in forums, especially fro beginners.
Redhat went from sysvinit (fedora < 9) over upstart (fedora 9-14) to systemd (fedora > 14; currently 19). optionally spitting out sysvinit scripts should be no rocket science...
