[nsd-users] Starting NSD on Debian with systemd fails

[Stephane Bortzmeyer]

Since I moved to Debian "jessie" which forces the usage of systemd,
NSD no longer starts when the machine boots. However, if I log in
immediately, and issue a "systemctl start nsd", it starts fine.

Otherwise, I get the message:

% sudo systemctl status -l nsd

I assume there is some dependency which is missing in the systemd
configuration files. May be NSD tries to start before the network? Any
NSD expert here?
