PSA: systemd-networkd segfault regression in Debian 13.1 for some users

The currently latest stable release of Debian (13.1) ships a broken version of systemd-networkd which may break networking completely for affected users. Maintainer response is less than encouraging: https://bugs.debian.org/1112535

> There was absolutely no need to disturb RT and waste your time, as you have much more important things to take care of, as this is just a minor issue with a particular corner case of a custom config of an optional component. Anybody who is unable to deal with that should just stick to the default Debian components. The next stable update in ~2 months will contain a fix.

"minor issue with a particular corner case of an optional component" my ass.

If you are currently on Bookworm using systemd-networkd with VLANs and bridges, you may want to hold off on the Trixie upgrade until fixed systemd 257.9 is available.
