The reason for GARCHIVEDIR is that stuff doesn’t get downloaded all over again every time
a spotless/package is done.

This seems wrong. It can clone from GARCHIVEDIR, but should then also pull from origin
and push back to GARCHIVEDIR.

Hmm… maybe checksums should contain the GIT Revision.

The Repo should be cloned and a new branch for patches in GAR should be created instead of
creating a new GIT Repository, this would make it easier to track patches. Also the cloned
repo in workdir/ could probably include a remote for garchive to permanently push patches
locally.

Yes :-)
