Yes, I just dug my way down to netplan, it actually looks like quite a
sensible approach to network configuration.

Yes, I agree.  However this headless system is going to back up
various services on my desktop system so I want it to be as similar as
possible.

I may end up leaving Network Manager in charge as it's *reasonably*
straightforward and I know how it works at present.  The only issue is
how to get to manage it remotely.  I guess I can just install xubuntu
with a real screen on the system and then just work remotely.  The
network interface is never going to change.
