[Yum] Custom Package Installation Conflicts

[Jay]

Thanks to everyone who replied to me on this issue.

It appears the only suitable workaround is to install the files into 
/tmp/ and then have the RPM manually copy the files to their final 
destination.

This isn't ideal as when an "rpm -qf <file>" is performed, RPM does not 
know that the file was actually installed by our custom RPM which can 
confuse people who aren't aware of all the files our RPMs install.

Seth are you set in your decision to not expose the RPM --replacefiles 
parameter in Yum?
Would you ever consider addressing this particular issue in another way?

I appreciate your time.

Kind Regards
Jay
