Solaris 10 non global zones and rc scripts

There are a handful of Solaris zones that run a rc3.d/ script (which is normal), however, there is a single script that runs during boot and removes itself upon completion. (This is known from viewing the script elsewhere on another box, which is apart of some legacy/defunct programs.) For whatever reason the script reappears after every boot of the zone and executed--which has been verified by browsing /var/svc/log/milestone-multi-user-server\:default.log The problem/question begins with this: **What in the world can cause the script to reappear in rc3.d/?** In fact, there is no rc2.d/ rc3.d/ init.d/ script which run beforehand that might cp the script over to rc3.d/, and the script itself does not seem to reside anywhere in the zone or global. And, a further note, I have not been able to find a (obvious) SMF service that might run a script to do the above action.
