In systemd based systems, such as debian 8 and ubuntu 16.04, I have this issue whereby the machine will refuse to shut down if I forgot to stop my openvpn connection before sending the command to shut down.
The command I use to start my openvpn connection is:
sudo openvpn --config client.conf --script-security 2
Is there a way I can change the command so systemd knows that it's okay to terminate it more quickly when the system is shutting down? Perhaps the alternative is to change systemd's timeout period to be much shorter? I would rather avoid any type of aliasing of my poweroff, halt, reboot, and shutdown commands.
