Maybe, patching the dbus service does not make much sense if we don't also build the systemd service file, I am going to see why that does not end up in the derivation. They are meant to be used together. One way or the other I think I am trying to make this build/output like dunst.

Closing, mako does not provide a systemd service file and does not officially support systemd activation. Does not seem worth doing ourselves either.
