Ah, thanks, I didn't know about that directory (and indeed there are a *lot*
of files in it - far more even than I'm used to seeing in old Debian machines'
/etc/udev/rules.d/ directories).

Firstly there are no references to eth0, eth1 or eth2 in any of those files,
and secondly the files are all older than Jan 1 2020, so clearly nothing has
been put there based on the hardware in this machine.

previously know about, even if it wasn't the solution to my problem.
