Yeah, maybe Git worktree could be used.  Aide the optimization of the
first “guix pull”, the current design is not totally safe when “guix
time-machine” is intensively run:

        The issue is because concurrency.  If two time-machines are run
        concurrently, they both update ~/.cache/guix/checkouts/ and the
        end result is hard to predict.

Yeah, but can we do better than mirroring Savannah and maintain a list
of supported mirrors?
