Description of problem:
When you execute systemctl stop tincd@network, the shutdown script in /etc/tinc/network/tinc-down is not executed. The reason is incorrect termination of tinc daemon.


Version-Release number of selected component (if applicable):
1.0.24-6.el7

How reproducible:
Always

Steps to Reproduce:
1. systemctl stop tincd@network
2. systemctl status tincd@network to watch output

I've fixed it by removing 

ExecStop=/usr/sbin/tincd -n %i -k

from tincd@.service

and adding

KillSignal=SIGTERM

though it would probably work without it.
