systemd resolved.conf, LLMNR=no?

Should we default to `LLMNR=no` on the default `/etc/systemd/resolved.conf`?

I mean, we don't ship samba enabled by default, why should we enable netbios NS replacement?

It is weird to see unexpected open ports listening on all public interfaces.

https://wiki.archlinux.org/title/Systemd-resolved#LLMNR

The board is the  wrong platform for this.
You'd file a bug at https://gitlab.archlinux.org/archlinux/ … d/-/issues but the reply is, likely, gonna be that the upstream defaults won't be changed and to file a bug at https://github.com/systemd/systemd/issues

But in terms of "TGN", archlinux should™ default to not shipping resolved itfp.

Re: systemd resolved.conf, LLMNR=no?

Systemd already has an open discussion to disable LLMNR by default : https://github.com/systemd/systemd/pull/28263. It will probably be disabled within a few releases.

LLMNR is used (almost) exclusively for single-label names in sd-resolved, so it's not really the disaster that it is on windows.
