Allow users to more easily alter mandos.service
The sysvinit script uses /etc/default/mandos as an environment file,
and supports adding additional server options to a DAEMON_ARGS
environment variable. This should be supported by the systemd
service, too.
* mandos.service ([Service]/EnvironmentFile): New; set to
"/etc/default/mandos ".
([Service]/ExecStart): Append "$DAEMON_ARGS".
