I created yum repo with copr.rpm: http://copr-be.cloud.fedoraproject.org/results/msuchy/copr/
It is for el6 and F18. I'm testing it on F18 right now.
I plan to test el6 later. I still yet did not packaged backend. But CLI and frontend should work. I also plan to do regular builds later. I mean something like nightly builds.
