I will just put in another plug for some work I had started around this (and never finished :-( ). https://review.openstack.org/#/c/83150/ (despite the Jenkins results, I'm pretty sure that was working locally for me) Also the discussion at http://lists.openstack.org/pipermail/openstack-dev/2014-February/026976.html There was general consensus on the approach and support has been in pbr for a long time now, but I've never had time to figure out what would be needed to make it play nicely with global requirements. I _think_ that's the only major blocker preventing this from being useful, so if someone wanted to pick it up and run with it that would be awesome. -Ben __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
