Thanks I will look into that.


I think it is not completely correct. For example if I do:
    systemctl status dummy

This gives as description:
    Unit dummy.service could not be found.

And the error code that is returned is 4.
I would not say that a non existing service is an interrupted service call.
I would find 22 (invalid argument) more logical. But it all depends how you
interpret things.
