One of the xubuntu 19.10 systems is a new install, the other has been
upgraded since quite a long way back.  As far as I can see all the
'resolv' links and configuration are the same on both systems.

On my two 19.10 systems /etc/resolv.conf is a link to /run/systemd/resolve/stub-resolv.conf

/run/resolveconf/resolv.conf doesn't exist on my systems.
