[$] An unstable Debian stable update

A bug in a recent release of systemd's network manager caused
headaches for people managing systems that have a virtual LAN (VLAN)
interface on a bridge; something one might want to do, for example,
when configuring network interfaces for virtual machines. The bug
affected several Debian users when upgrading the systemd package
from v257.7-1 to v257.8-1. The updated package is part of the Debian 13.1
release, and the bug has snared enough users to cause a minor
stir—due in no small part to the maintainer's response as much
as the bug itself.
