We currently have a "side repo" available for testing:
http://repos.fedorapeople.org/repos/openstack/openstack-folsom/epel-opens...
http://repos.fedorapeople.org/repos/openstack/openstack-folsom/epel-6/
A group of us are planning to run through as many of
the Fedora 18 test day tests this Friday.
https://fedoraproject.org/wiki/Test_Day:2012-09-18_OpenStack
We'll be hanging out on #fedora-openstack on freenode.
All going well, OpenStack Folsom will be added
to EPEL 6 in a week or so.
thanks,
Pádraig.
