BTW, we had a discussion about this particular idea at the Virt SIG
meeting, and KB said that different naming of packages like this can
cause dependency problems.  For example, a package depends on
"xen-version >= $N" will fail because as far as rpm is concerned, you
don't have package 'xen' installed at all.

Another idea is to keep separate repos, and then have
"centos-release-xen-$VERSION", which would always point to $VERSION,
and "centos-release-xen", which would always be the newest version.
That might satisfy both types of people.
