Posting bellow is written with intend to avoid waiting until “koji” build will appear in updates repo of stable RDO Mitaka release, what might take a couple of months or so. Actually, it doesn’t require knowledge how to write properly source RH’s rpm file. It just needs picking up raw content of git commits from upstream git repo converting them into patches and rebuild required src.rpm(s) with patch(es) needed. There is also not commonly known command `rpm -qf` which is very useful when you need to detect which rpm has installed particular file. Just to know which src.rpm should be downloaded for git commit referencing
say “cinder.rb”
