The Fedora repo for the Havana-2 packages is mixed up a bit. While the repo is called fedora-19, the packages in it are almost all built for F20 (i.e. they have fc20 in their dist tag). That's a bit worrisome, as things could get different enough between a F19 and F20 build host so things start misbehaving or failing otherwise. Is there a chance to actually build F19 packages on F19 build hosts?

Also, since F20 packages are apparently being built, I wonder why no fedora-20 repo is created. The earlier such a repo exists, the earlier we can test the packages and make RDO work on F20. That could help avoid the situation as-is with F19+RDO, where lots of things are broken pretty bad and need workarounds. I know, technically one can just use the fedora-19 repo with F20 but it would make things easier to have a separate fedora-20 repo and it will become necessary once there's real F19 packages in the fedora-19 repo, anyway.

At the same time, it should be noted that Packstack is currently not working on un-branched F20, i.e. Rawhide. Three Puppet modules need each a fix, which have been sent upstream now. The rather small issue is that the operatingsystemrelease fact does not return an Integer as expected but the string "Rawhide" on such systems.
