Yes, that a nice clarification.  It's a good reason why the 1.7 version
of a package should always be > the 1.5 version.

This has absolutely nothing to do with union-fs.  It does have to do with
eliminating confusion.

I haven't done an exhaustive test to make sure that this is true but I'm
pretty sure that RHEL and Fedora don't share the same packages either.

This really shouldn't be a big issue right now anyway.  I don't see why
anyone would be going to a lot of effort to support 1.5.  We really should
be in feature freeze right now.
