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.
