nixos/avahi-daemon: resolve mdns only over enabled protocols, disable ipv6 by default

see https://github.com/lathiat/nss-mdns#:~:text=in%20such%20a%20situation%20causes%20long%20timeouts%20when%20resolving%20hosts
especially:
> libnss_mdns.so.2 resolves both IPv6 and IPv4 addresses, libnss_mdns4.so.2 only IPv4 addresses and
> libnss_mdns6.so.2 only IPv6 addresses. Due to the fact that most mDNS responders only register local IPv4
> addresses via mDNS, most people will want to use libnss_mdns4.so.2 exclusively. Using libnss_mdns.so.2
> or libnss_mdns6.so.2 in such a situation causes long timeouts when resolving hosts since most modern
> Unix/Linux applications check for IPv6 addresses first, followed by a lookup for IPv4.

Raw Blame History

Release 24.05 (“Uakari”, 2024.05/??)

Support is planned until the end of December 2024, handing over to 24.11.

Highlights

In addition to numerous new and upgraded packages, this release has the following highlights:

screen's module has been cleaned, and will now require you to set programs.screen.enable in order to populate screenrc and add the program to the environment.

New Services

Guix, a functional package manager inspired by Nix. Available as services.guix.
maubot, a plugin-based Matrix bot framework. Available as services.maubot.
Anki Sync Server, the official sync server built into recent versions of Anki. Available as services.anki-sync-server. The pre-existing services.ankisyncd has been marked deprecated and will be dropped after 24.05 due to lack of maintenance of the anki-sync-server softwares.
Clevis, a pluggable framework for automated decryption, used to unlock encrypted devices in initrd. Available as boot.initrd.clevis.enable.

Backward Incompatibilities

mkosi was updated to v19. Parts of the user interface have changed. Consult the release notes for a list of changes.
services.avahi.nssmdns got split into services.avahi.nssmdns4 and services.avahi.nssmdns6 which enable the mDNS NSS switch for IPv4 and IPv6 respectively. Since most mDNS responders only register IPv4 addresses, most users want to keep the IPv6 support disabled to avoid long timeouts.

Other Notable Changes

addDriverRunpath has been added to facilitate the deprecation of the old addOpenGLRunpath setuphook. This change is motivated by the evolution of the setuphook to include all hardware acceleration.
Cinnamon has been updated to 6.0. Please beware that the Wayland session is still experimental in this release.
Programs written in Nim are built with libraries selected by lockfiles. The nimPackages and nim2Packages sets have been removed. See https://nixos.org/manual/nixpkgs/unstable#nim for more information.
The Yama LSM is now enabled by default in the kernel, which prevents ptracing non-child processes. This means you will not be able to attach gdb to an existing process, but will need to start that process from gdb (so it is a child). Or you can set boot.kernel.sysctl."kernel.yama.ptrace_scope" to 0.
Gitea 1.21 upgrade has several breaking changes, including:
- Custom themes and other assets that were previously stored in custom/public/* now belong in custom/public/assets/*
- New instances of Gitea using MySQL now ignore the [database].CHARSET config option and always use the utf8mb4 charset, existing instances should migrate via the gitea doctor convert CLI command.
The hardware.pulseaudio module now sets permission of pulse user home directory to 755 when running in "systemWide" mode. It fixes issue 114399.
QtMultimedia has changed its default backend to QT_MEDIA_BACKEND=ffmpeg (previously gstreamer on Linux or darwin on MacOS). The previous native backends remain available but are now minimally maintained. Refer to upstream documentation for further details about each platform.
