With my Debian Developer hat on, I'd like to send a reminder ...

When Wheezy will be released, we'll have Essex in (if everything goes as
planned). Then when Wheezy +1 gets out, will will also need to allow an
upgrade path for Openstack (otherwise, it's considered an RC bug in
Debian). And I believe that Ubuntu will have the issue as well (since
2012.4 will be an LTS, right?).

I just hope that Openstacker will keep in mind how much of a commitment
it is to allow upgrade from release to release + 4 (or +5) in a project
like Openstack which goes so fast. :)

Cheers,

Thomas
