This appears to be the key part of this usecase.  The various union
mounting bits didn't exist when this code was written.

In *this particular* use case, the correct semantics is to leave the
mount alone, together with any directory needed as scaffolding.  This is
somewhat noteworthy that some other use cases which have been proposed
have different requirements.

I would prefer this to bee an option, e.g. --keep-mounts, but perhaps
that's overkill?
