This is deeply upsetting https://mastodon.social/@lambdageek/116099461735423343
Another upsetting thing: Apparently systemd has its own mdns setup: https://www.reddit.com/r/debian/comments/1mnvzln/the_debian_technical_committee_made_a_baffling/ which Debian may, or may not, have disabled intentionally in Debian 13 (the file this poster claims is present is not present) because they expect they use Avahi instead. I don't understand why I'd use Avahi instead of systemd, or, if I decided systemd's mdns were better, how I'd switch to it.
