Does "system upgrade" mean more than, say, apt-get upgrade?

I recognise that MAC. You posted about it in January. You were running
it with iwd. Why is systemd-udevd trying to rename the interface?
Do you still have the file:
$ cat /lib/systemd/network/80-iwd.link
[Match]
Type=wlan
[Link]
NamePolicy=keep kernel ←←←←←←←←←
$
or your own version under /etc?
Or has the upgrade tried to revert the system back to a more
conventional ifupdown/wpa configuration in some way?
