A mock config for C5 building was posted, to the Centos-devel list, the appropriate place for such. Here's a link to an archive copy: http://lists.centos.org/pipermail/centos-devel/2007-August/001910.html Read through that thread again....shouldn't take too long, since there's only two messages. Note the date, and note the posters. For building a 5.6 of your own this should help, along with the el5 buildsys RPM (which only contains requires for the basic buildsys) that's already been posted about. For building a 6 of your own, the Fedora process, while tuned to a much larger project, uses koji and all that entails, is available and completely open (to the best of my knowledge). The Mass Rebuild scripts live at http://git.fedorahosted.org/git/?p=releng Note that a full koji is fully required by those scripts, but there they are. Far more than just a simple mock config.....but that's because of the size of the project, and the fact that it has a distributed build system. There is plenty of documentation on how to do a Fedora rebuild yourself on the Fedora project wiki. And, not to beat a dead horse, but EL6 is based off F12, and thus, once you have comps and a few things, in theory the Fedora infrastructure, loaded with all the buildrequires (a larger package set than the distributed SRPMS) for EL6, would churn out EL6 builds and composes. Now, I mentioned the build requires. Poking around in my local copy of the 6rolling tree of SL, I find that there are packages required to build SL6 that are not part of SL6, and live in a separate directory ( ftp://ftp.scientificlinux.org/linux/scientific/6rolling/build/ to be specific). I don't see the mock config or build scripts, however; perhaps I'm not looking in the right place.....
