I gave it some thought.  I haven't tested anything.  Existing magic
should work for most installs since there's still a "kernel" package
and that's what yum keys off of.  If/when we do this, I'll certainly
test more carefully to make sure.

That brings up a question though, how often would cloud expect to do a
yum update of individual packages as opposed to just updating the
entire image?  If we expect the 3 kernel magic to work there, then
some changes to yum/dnf may be required given that Cloud would be
explicitly specifying "kernel-core" and not "kernel".
