On the Koji community call yesterday, a point was raised that mock bootstrap support[0] in Koji is needed in order to support epel 6 builds.  I'd like to dive into that a bit more to better understand the problem and the options. 

Kevin, if I understand correctly, this would become an issue when F31 is deployed on the builders.  About when would that be and when does epel 6 need to be supported until?
