This is fixed in git now, thanks!

It worked before and it still works for me.

I don't see why it should fail for this reason ?

systemctl edit getty at .service, should have worked before so yes this was a bug.

systemctl edit try to use the bus if it is possible, because this is
the only way you can know where is the unit file of the unit
foo.service currently running. Is it in /etc/systemd or
/usr/lib/systemd? If we check directly the file system we will assume
this is the first directory with the highest priority, which is wrong
in some cases.

But systemctl edit wanted to work with valid unit names which is wrong
in some cases too, so this is fixed now.

Thanks for the report!
