This bug is currently being QA'd for an async release of RHOS 3.0/Grizzly.

It is not yet released for RHOS 3.0 since it is still in testing.  It
should be updated soon on our content mirrors (Red Hat Network)

If it is not a candidate for the stable branch of Grizzly, then it
wouldn't be in RDO Grizzly as RDO follows the upstream stable branches.

Vladan, since you are working on this, did it get proposed for the
stable branch or is it RHOS only backport?

Since this is RDO related, I'm going to move this thread over to rdo-list.
