Nope, not really.
But it is as easy as this: when we stop a service the "KillMode=" option
controls whether and how any processes remaining after the "ExecStop="
command (if there is such a command, and if there are any processes left)
KillMode=control-group → the entire cgroup is shot down
KillMode=process-group → only the process group of the process we forked is shot down
KillMode=process → only the process we forked is shot down
KillMode=none → nothing is shot down
