I haven't tried that because I'm not replacing a package.  Both packages still exist on the system and are both needed, it's just that ownership of one of the files is being transferred from one package to another.  Would I still use RREPLACES even if I want to keep both packages on the system?

Specifically in this case, I have some script files for scheduled tasks that were part of one of my self-made packages.  However, they really belong with cronie since this is what is calling the scripts.  So I removed the script files from my self-made package and added them to cronie.  My package has other files still associated with it (that do belong with it) installed on my system.  So I want to keep both packages on my system, but I just want to change ownership of these script files from my package to cronie.  Is RREPLACES the tool for this job?

Thanks,
Bryan
