Resuming this thread so I get some direction to proceed with.

So, docker in Virt SIG used to be Fedora rpms recompiled. But, the
requirement for multi-docker installation on RHEL made us feel the need to
try it out on Virt SIG as well.

The RH patchset will be the same for both Fedora and RHEL, just that RHEL
could have approaches (like docker and docker-latest)
Fedora would never agree to.

I'd like to zero in on a single approach moving forward.

So, pick one. CentOS Virt SIG docker will have:

1. Fedora rpm rebuilt
OR
2. RHEL rpms (docker + docker-latest) rebuilt (consider it a preview or
something before official release)
OR
3. Something else, maybe both Fedora and RHEL versions clearly separated by
koji tags
