Not really, because it is then also needed to do priority-overriding
of the configuration snippets by hand. I would really like to avoid re
-implementing this logic.

There is an alternative to bind-mount all configuration directories
into the destination root, but it's not "atomic" against killing of
the process (if we get killed in between, stale bind mounts will
remain). So I won't like to do this either. I'm sure that mkinitcpio
maintainer in arch will not accept this solution as well.

Any other options?
