Well, in the repository there are no config files, just the default and
cdiffs.

OK, so you manually select/deselect new drivers in the default config
only, and the hope is that the diff files can take care of that. My only
concern here is, that the diff files do not appear to play nicely with
git rebase/merge, as those functions apply diffs to diffs.

True, it applies the default values to all new options, it does not need
manual intervention though. If we really can use cdiffs _without_
_touching_ them _after_ an upgrade, that would be beneficial.
