Open Stack

My opinion as one of RDO release wranglers is not to support Fedora
for anything else that isn't trunk.
It's proven really hard to maintain all dependencies in a good state,
and when we managed to do that,
an update could break things at any time (like python-pymongo update
who was removed because of Pulp developers).

RDO actually ensure that spec files are buildable on Fedora but you'd
have to maintain dependencies separately and rely on
tools like yum priorities plugin to override base packages.

Fedora lifecycle is also not sync-ed with OpenStack, OpenStack being
released around 2 months before the next Fedora Stable.
So in practice, if you use stable N-1, you have 9 months of support
from Fedora, and updating to stable N requires some amount of work.
