I understand that ^Q will make procServ to exit, but I do not want to
know when I need to send it. IOW, what I'm after is, if an IOC dies,
procServ needs to exit by itself without user intervention and let the
systemd take over and restart the service (procServ).
If I understand the 'ExecStop=' correctly it is executed when the
service is being stopped, i.e. when user does:

$ sudo systemctl stop [email protected]

Again, for my case, procServ would need to exit on the behalf of
clients death, and not as a consequence of users actions (sending ^Q
or issuing systemctl stop).

I must be missing something, because I fail to recognize the suggested
approaches as viable solution for me.

Thanks,
Hinko
