The PR #282377 made files/directories specified in
`environment.etc."pipewire<...>"` and `environment.etc."wireplumber<...>"`
conflict with existing configuration of the PipeWire NixOS module due to how
the `configPackages` options were implemented. This sadly wasn't easily
avoidable. As this can cause breakage for users moving from 23.11 to 24.05
though, assertions can help guide them to use `services.pipewire.extraConfig`
or `services.pipewire.configPackages` / `services.wireplumber.configPackages`
instead, fixing the breakage.
This drops a whole bunch of patches we carry to avoid output cycles, at the cost of +1MB to closure size
on systems that don't already have Pipewire, which are becoming rarer and rarer.
- drop media-session (rip 💀)
- stop trying to let people override default configs, those never got merged correctly
- drop all the complexity arising from having to vendor default config files
- build docs in sandbox as we no longer recurse
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
An empty LD_LIBRARY_PATH may confuse some applications into appending
:, creating an empty segment that insecurely refers to the current
directory, not the absence of directories.

Currently, default options for media-session are empty, making it harder
to adapt them without fully overwriting them. This commit sets these
defaults to the content of the JSON files provided with media-session.
