Comment 6 for bug 1718227

I have a problem with tinc and netplan.

I've using Ubuntu 17.10 server. When I try to start tincd daemon with systemd, it doesn't start.
When start tinc daemon without systemd, it runs correct.

Fail:
crashbit@sun:~$ sudo systemctl start tinc
crashbit@sun:~$ sudo systemctl status tinc

Succes:
