Steve,

Regardless of the upgrade path, I'd pretty much prefer publishing Xen
4.3 packages in a separate repo for production, say kernel-xen-xen43,
disabled by default. This way we can get the best of both worlds:
- People stuck with 4.2 will continue to use it, while:
- Early 4.3 adopters will have the ability to run tests and contribute
  to the cause without affecting 4.2 users.
Although, I know maintaining yet another repo isn't exactly on your
personal wishlist :)
