http://linux.dell.com/files/fedora/FixBuildRequires/ftbfs-nov08.tgz
has the scripts I use (only slightly changed since that tarball was
made, and not critically), to do my whole rawhide rebuilds.

That said, these are ugly.  They work, but make quite a few
assumptions due to the lab environment _I_ have.

As this need has arisen several times across the project, I think it
would be worthwhile to have a clean method to do this that doesn't
make such assumptions.  I simply haven't had time to do it, but would
welcome the effort.

Architecturally, you want to use mock to do all the builds, pointing
at your local copy of the F12 repositories (base + updates) to be used
as the build roots.  Then you want to loop over all of the packages
you want to rebuild, invoking mock for each.  This is what my scripts
do.  Salt to taste.

Thanks,
Matt
