(There a decent chance that I'll be working on this within the next couple of months regardless of interest, but knowing that someone else might contribute or benefit from it helps for motivation...) This work has been done; it's called koji. From my quick reading this morning, it's probably a safe speculation that RHEL6 was built with a Red Hat-internal koji instance. ( http://www.redhat.com/archives/epel-devel-list/2010-December/msg00128.html ) Koji is proven technology; it gets a continuous workout building Fedora. And it has a learning curve; perhaps working through the problem the hard way first could be educational; perhaps seeing how a large extremely open project went about it could be just as educational, it depends upon what you want to learn, and where you want to spend your time.
