If the parent domain is hosted elsewhere, you should not load it as a
master locally...

No, you do not need to load the parent domain (you called it
masterdomain) to load a sub domain.  However, the parent domain MUST
delegate the sub domain to you.  Therefore, in the parent zone file you
would need this:

; Delegate sub domain by specifying an NS RR for it:
sub.berghoff-familie.de.	NS	linux.sub.berghoff-familie.de.

; Provide Glue RR to tell everyone the IP of the NS in this domain:
.sub.berghoff-familie.de.	A	<external IP of name server>

You do not need to load the master, drop it...

This zone specification is what you do need, keep it...

Lose this zone file, it is not needed, the zone is loaded by someone
else...
