Ok, so meaybe there is something missing. I remember having tested the

I see. But we should ignore the status unless it's 4, right?  I think
the current logic of the unit file should behave exactly like that, at
least that is the intention :) But it can be stopped with "systemctl
stop freerouter", of course.
