I use the default /var/lib/nsd/nsd.db, that's what I meant with db, just
"database".

Yep, that's true, but I'm too lazy sometimes :)

I just had a glance at nsd-control it and indeed, I think it is nicer to
invoke an "nsd-control reconfig" instead of telling the supervisor to
restart nsd.

OTOH, nsd does not read its config file when receiving a HUP. It would
be a nice if a USR2 would force a config reload in case of a supervised
setup. Maybe that's something for the wishlist.
