Hmm -- so I take it that /etc/sysconfig/xen-kernel is now a part of
the xen package...?

One issue with this is that during normal Xen development I often make
an RPM directly from the upstream repo, so while I have the xen4centos
kernel & libvirt installed, I don't have a xen4centos xen installed.

The nice thing about the current script in centos-release-xen is that
it works with non-x4c xen packages.

Sorry I hadn't thought about that side-effect when you mentioned this
before. :-/

Any thoughts?  Would it be possible to have the script in
centos-release-xen and check for the existence of /boot/xen.gz, for
instance?
