Hello guys,

I tried that and it _seems_ to be working, BUT:

running `service kamailio start` just stays there and fails after about a
minute:

Job for kamailio.service failed. See 'systemctl status kamailio.service'
and 'journalctl -xn' for details.

running systemctl status kamailio.service replies with:

Is it possible systemd is taking those "ERROR"s as an indication the
service is not starting properly? Even though it is?

my service unit file is like so:

~# cat /etc/systemd/system/multi-user.target.wants/kamailio.service
[Unit]

Thanks everyone.
