After a short visit to Linux Solutions in Paris, I've been working with Xavier Lamien on setting up Koji for RPM Fusion. We would make full use of the External Repository support, in order to import Red Hat Enterprise Linux (RHEL), CentOS, Extra Packages for Enterprise Linux (EPEL) and Fedora, so that packages can be built for Enterprise Linux 4 & 5, Fedora 11, 12, 13 and Rawhide.
Working on such, I thought it would be nice to share a few details on the subject, such as the way I've set up tag inheritance + external repositories + free + nonfree in RPM Fusion. Hence, here's a overview diagram of how it's set up. I've also made a more extensive document on the subject, for those of you wanting to set up there own buildsystem. This however will probably become a book sometime.
