  a Proxmox upgrade."

So, after upgrading Proxmox from version 6.x to 7.x, the network
was suddenly gone. Turns out, the network service wasn't started anymore.

According to `systemctl`, it was disabled.
After some googling, it seemed to be that this was because
I was doing was the Debian docs were saying, performing
an `apt purge`, deleting the `ifupdown` configuration. This seemingly
disabled `networking.service`.

So I symlinked the unit into `/etc/systemd/system/default.target.wants`, rebooted
and everything was fine again. Thank godness for physical access to hardware.
