How is that better than

    systemctl stop NetworkManager
    systemctl disable NetworkManager

Again, I’m not really after a way to make this work without NetworkManager.  We’ve already got that.  What I want is a way to tell NM to obey the MAC binding.  This configuration *here* goes with that MAC chip *there*.

Given that, we don’t need to disable NetworkManager.
