Even semi-stable would be agreeable as a start. If the various distros
and users who want to package Xen focus their efforts on that single
repository, it 'semi' could be dropped very quickly.

That's what I was proposing. Just CVE's and major bugfixes would do just
fine. If people want fixups in a file system, they can just cherry pick
on their own. The idea being customers of that repo only need to update
their deployments when something really scary or really juicy is pulled.

An example of juicy: the stuff Dan is working on. There's no reason why
new experimental features can't go into the static tree, that keeps them
from cluttering Jeremy's workspace while getting them attention and
testing.

Yes. If -stable can keep up with (or one version behind) mainline, the
whole sense of urgency to see everything merged goes down to a dull
roar.

Its not just users, integrators and developers who have been watching
these lists for the last few weeks .. its also our customers.
