- <para>If set to <option>control-group</option>, all remaining

- unit stop (for services: after the stop command is executed,
- as configured with <varname>ExecStop=</varname>). If set to
- <option>process</option>, only the main process itself is
- killed. If set to <option>mixed</option>, the
- <constant>SIGTERM</constant> signal (see below) is sent to the
- main process while the subsequent <constant>SIGKILL</constant>
- signal (see below) is sent to all remaining processes of the
- unit's control group. If set to <option>none</option>, no
- process is killed. In this case, only the stop command will be
- executed on unit stop, but no process be killed otherwise.
- Processes remaining alive after stop are left in their control
- group and the control group continues to exist after stop
- unless it is empty.</para>

- enabled with <varname>SendSIGHUP=</varname>). If then, after a
- delay (configured via the <varname>TimeoutStopSec=</varname>
- option), processes still remain, the termination request is
- repeated with the <constant>SIGKILL</constant> signal (unless
- this is disabled via the <varname>SendSIGKILL=</varname>
