Without this, you get the following error message in the logs:
udisksd[4082]: Failed to load config files: Failed to get contents of the config dir (/etc/libblockdev/conf.d/)Error opening directory “/etc/libblockdev/conf.d/”: No such file or directory. Using the built-in config
It's a very useful backend (that probably should be enabled by default,
like on Ubuntu), let's start by making it easier to discover.
Ref https://github.com/NixOS/nixpkgs/issues/28406.
Point $SANE_CONFIG_DIR and $LD_LIBRARY_PATH to symlinks in /etc, instead
of directly to nix store paths, so that activating a new configuration
takes effect immediately, instead of requiring users to re-login.
The polkit support in pcsclite is entirely optional but package enables
it unconditionally and this breaks connecting to the pcscd daemon on
systems without polkit.
The fix is making this configurable and automatically disabling
`polkitSupport` when the polkit service is disabled.
We are building fwupd daemon with polkit support which means
polkit daemon is required.
Previously polkit was enabled by default via udisks2 but that
stopped with f763710065
breaking the fwupd installed tests as a result.
Let’s add the polkit dependency to the fwupd module to ensure polkit is available.
most of these are hidden because they're either part of a submodule that
doesn't have its type rendered (eg because the submodule type is used in
an either type) or because they are explicitly hidden. some of them are
merely hidden from nix-doc-munge by how their option is put together.
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.
mostly no rendering changes. some lists (like simplelist) don't have an
exact translation to markdown, so we use a comma-separated list of
literals instead.
In version 1.5.5 of fwupd the uefi plugin was renamed to
uefi-capsule. As part of those changes the configuration file was
renamed and changed.
This modules configuration mismatch was generally hidden because
when udisks2 is enabled fwupd will use that instead. Without
udisks2 the following warning is seen:
WARNING: UEFI ESP partition not detected or configured
This was enabled by default in 18a7ce76fc
with the reason that it would be "useful regardless of the desktop
environment.", which I'm not arguing against.
The reason why this should not be enabled by default is that there are a
lot of systems that NixOS runs on that are not desktop systems.
Users on such systems most likely do not want or need this feature and
could even consider this an antifeature.
Furthermore, it is surprising to them to find out that they have this
enabled on their systems.
They might be even more surprised to find that they have polkit enabled
by default, which was a default that was flipped in
a813be071c. For some discussion as to why
see https://github.com/NixOS/nixpkgs/pull/156858.
Evidently, this default is not only surprising to users, but also module
developers, as most if not all modules for desktop environments already
explicity set services.udisks2.enable = true; which they don't need to
right now.
- improve some descriptions
- device -> devices
- add options
- extraArgs
- port
- create a symlink in RUNTIME_DIRECTORY
- grant it read permission of /dev/uinput
- relax network-related restrictions when port is used

now nix-doc-munge will not introduce whitespace changes when it replaces
manpage references with the MD equivalent.
no change to the manpage, changes to the HTML manual are whitespace only.
make (almost) all links appear on only a single line, with no
unnecessary whitespace, using double quotes for attributes. this lets us
automatically convert them to markdown easily.
the few remaining links are extremely long link in a gnome module, we'll
come back to those at a later date.
we can't embed syntactic annotations of this kind in markdown code
blocks without yet another extension. replaceable is rare enough to make
this not much worth it, so we'll go with «thing» instead. the module
system already uses this format for its placeholder names in attrsOf
paths.
our xslt already replaces double line breaks with a paragraph close and
reopen. not using explicit para tags lets nix-doc-munge convert more
descriptions losslessly.
only whitespace changes to generated documents, except for two
strongswan options gaining paragraph two breaks they arguably should've
had anyway.
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.
This should be a significant disk space saving for most NixOS
installations. This method is a bit more complicated than doing it in
the postInstall for the firmware derivations, but this way it's
automatic, so each firmware package doesn't have to separately
implement its compression.
Currently, only xz compression is supported, but it's likely that
future versions of Linux will additionally support zstd, so I've
written the code in such a way that it would be very easy to implement
zstd compression for those kernels when they arrive, falling back to
xz for older (current) kernels.
I chose the highest possible level of compression (xz -9) because even
at this level, decompression time is negligible. Here's how long it took
to decompress every firmware file my laptop uses:
i915/kbl_dmc_ver1_04.bin 2ms
regulatory.db 4ms
regulatory.db.p7s 3ms
iwlwifi-7265D-29.ucode 62ms
9d71-GOOGLE-EVEMAX-0-tplg.bin 22ms
intel/dsp_fw_kbl.bin 65ms
dsp_lib_dsm_core_spt_release.bin 6ms
intel/ibt-hw-37.8.10-fw-22.50.19.14.f.bseq 7ms
And since booting NixOS is a parallel process, it's unlikely (but
difficult to measure) that the time to user interaction was held up at
all by most of these.
Fixes (partially?) #148197
First, add the builtin udev rules to /etc/udev/rules.d so they are used.
Then, add all networkd .link units to the initrd. This is done in the
old stage 1 as well so I assume this is needed even when networkd is not
used. I assume this is for things like changing the MAC address.
Also limit the number of udev/lib binaries that is put into the initrd
because the old initrd doesn't use all units either.
One of the valid values for the fan speed is "level disengaged",
however, it is represented as "level disengage" and does not match
what thinkfan expects.
adds defaultText for all options that use `cfg.*` values in their
defaults, but only for interpolations with no extra processing (other
than toString where necessary)
NixOS should be able to support the Nintendo Switch Pro controller for
steam and non-steam at the same time. Currently there are two mutually
exclusive ways to support the Pro Controller: Steam and `hid-nintendo`.
Unfortunately these don't work together, but there's a workaround in
newer versions of `joycond` (described [here](https://wiki.archlinux.org/title/Gamepad#Using_hid-nintendo_pro_controller_with_Steam_Games_(with_joycond))). To use this
workaround `hid-nintendo` and `joycond` need to be updated, and the
systemd and udev configuration needs to be made available in NixOS.
The attributes got renamed in PR #126440 and in some places this caused
evaluation errors, e.g. the tarball job was saying (locally)
> attribute 'alsaUtils' missing, at /build/source/nixos/modules/services/audio/alsa.nix:6:4
and I suspect that trunk-combined jobset's failure to evaluate was also caused.
