You need to make sure you understand that the "name" does not contain .rf,
.plus or otherwise. That is (generally) part of the Release String. RPMs are
named in a Name-Version-Release.Arch pattern.
This has been discussed on the yum mailing list previously, and it is
difficult (at best) to track what repository an RPM came from, especially
when RPMs are installed by hand, repositories are removed, etc. The RPM
database does not allow for this information in its current implementation.
In order to implement what you suggest above goes beyond yum into RPM-land.
Either way, this probably isn't the right mailing list for this discussion.
