Exactly. Deploying from a source stable branch should be viable - as it
stands, it is not. One of the tenets of a stable branch must be repeatable
from-source builds.

Right now I have "effective pins" in my mitaka Ansible playbooks for kombu
and keystonemiddleware. This latest kombu kerfuffle broke stable/mitaka
glance, neutron and nova for me. Keystone broke a few days ago.

Is there an existing effort or blueprint or whatever being worked on for
pinning (or at a minimum setting upper bounds on) dependencies in stable
branches? If so, I would like to follow and/or participate.
