Hi

openntpd was just one example of the issue. I tried setting After=network-online.target before opening this bug, it has no effect and is why I mentioned "xenial server (dunno about desktop) doesn't seem to use network-online.target".

ubuntu@xenial64:~$ systemctl list-dependencies network-online.target
network-online.target
● └─networking.service

network-online.target will be complete as soon as networking.service (ifup) has finished configuring interfaces. You can see this in my log output.
