Well. The Windowization of Linux via systemd-* seems to be inexorable. But we must put in a wooden slap to kill systemd-networkd here and now: it’s deleting routes and addresses randomly, killing BGP routing. I’m plagued by contemporary linux systems loosing v6 default routes or v4 address configurations, and I’m fed up with it.
None of that shit happened before cancerous systemd hit the scene; therefore I consider systemd a viroulent and toxic add-on to any server-type Linux installation. While »apt purge systemd« seems to be possible in Debian 12, I wonder how many times I’ll ›win‹ a re-installation of systemd when installing any third party or Debian-supported SW?
Seriously, systemd-geraffel: Get. Off. My. Lawn!
