I interpreted that as "from now on, systemd will not restart the 
service, but it will not stop the running service". So that when I 
manually killed the daemon, I expected it to _not_ start it.....

But I don't want to _stop_ the service. I want the running service to 
not restart when/if it dies.

That page does not really show me an option on how to prevent a restart 
_from now on_,

Since this still does not work:

systemctl disable ipsec.service
systemctl stop ipsec.service
systemctl start ipsec.service

This causes the restart behaviour to restart it again.

So my original question still is, can i temporarily disable 
Restart=always without changing the service file on disk and sending a 
system-daemon reload?
