I think this is related to the use of /usr/lib/tmpfiles.d/nsd.conf in
the sysv initscript.  I stumbled over this over the weekend, and was
having a look to see if it's already been reported and found this bug
which seems to match.

On my system (a RaspberryPi with raspian stretch) it manifested
slightly differently, but I think mostly because I restarted the
process, rather than init trying to start the daemon after a fresh
boot.

In my case the directory was already in place, with the correct
ownership and mode, so all I got was the complaint from `chown`, which
on it's own wasn't fatal.

The cause, in my case at least, is the way `while read` is used in the
initscript as it ignores the (unused) age and arguments options.  The
attached patch appears to fix it for me, hopefully it'll also work for
you.

Cheers.

Dameon.
