Thanks for getting this started!

Sounds good. I'll create branches in gerrit named 'diablo' branching
from the commit with the 2011.3 tag. I think we can update the release
management process to incorporate this step for essex.

My preference is to only have branches in gerrit and on github where we
are actively accepting changes. Otherwise it may appear that we would
accept proposed changes to diablo indefinitely. So I'd like to suggest
that when the maintainers stop maintaining the branch that we tag the
last commit and then remove the branch. We won't lose any information
this way; the tag alone is enough to access the commit history of the
branch. This is the current process in place for milestone-proposed.

Are you planning on grepping commit logs for that, or are you asking
people to email that address?

Permissions in gerrit can be configured on a per-branch basis.
Currently, we let anyone +/-1 a change, and only core devs can +/-2. A
strict analog would be to continue to allow general +/-1 feedback and
only members of the maintainers team or core devs can +/-2. How does
that sound?
I've created a group in Launchpad, openstack-stable-maint ("Openstack
Stable Branch Maintainers"), that I'll give permission to approve
changes to stable branches in Gerrit. As we discussed an the summit,
I've added Chuck Short, Dave Walker, and Mark McLoughlin as admins to
that group; they can approve membership applications.
Thanks again for writing this up!
