The single option tries to do too much work, which just ends up confusing people.
So:
- don't force the console font, the kernel can figure this out as of #210205
- don't force the systemd-boot mode, it's an awkward mode that's not supported
on most things and will break flicker-free boot
- add a separate option for the xorg cursor scaling trick and move it under the xorg namespace
- add a general `fonts.optimizeForVeryHighDPI` option that explicitly says what it does
- alias the old option to that
- don't set any of those automatically in nixos-generate-config
Updates the warnings message for statefully set up passwords, now that
weak algorithms have been removed from our libxcrypt package.
Additionall we now add proper validation for hashing schemes used in
`hashedPassword`.
Neither will prevent a rebuiild, but instead issue a warning, that this
requires immediate remediation, or else users will be unable to login.
Reuses the crypt scheme ids as provided by the libxcrypt package.
Without this change, users that have both `initialHashedPassword` and
`hashedPassword` set will have `initialHashedPassword` take precedence,
but only for the first time `/etc/passwd` is generated. After that,
`hashedPassword` takes precedence. This is surprising behavior as it
would generally be expected for `hashedPassword` to win if both are set.
This wouldn't be a noticeable problem (and an assert could just be made
instead) if the users-groups module did not default the
`root.intialHashedPassword` value to `!`, to prevent login by default.
That means that users who set `root.hashedPassword` and use an ephemeral
rootfs (i.e. `/etc/passwd` is created every boot) are not able to log in
to the root account by default, unless they switch to a new generation
during the same boot (i.e. `/etc/passwd` already exists and
`hashedPassword` is used instead of `initialHashedPassword`) or they set
`root.initialHashedPassword = null` (which is unintuitive and seems
redundant).
From SuperSandro2000's post-merge review of the PR adding this,
nixos/no-x-libs: add qtbase. Sandro added a comment about this after I had
already merged it; self'/super' previously masked the top level self/super.
mkAliasOptionModule should not default to mdDoc descriptions because
that can break out-of-tree users of documentation infrastructure. add an
explicitly-MD variant for now, to be removed some time after the MD
transition is complete.
Introduce a `users.users.<name>.expires` option to allows setting an
expiry date to user accounts.
This is useful when members should gain temporary access and you don't
want to have to roll out another system update to disable them.
To allow for a reasonably fast deprecation of weak password hashing
schemes we provide an activation script that checks existing hashes in
/etc/shadow and issues a warning for user accounts that still rely on
deprecated hashes.

Icon caches should be generated for directories under $out/share/icons, as the comments mention, but it is done for files as well which does not make the build fail but results in files under $out/share/icons being turned into empty directories, see /run/current-system/sw/share/icons/gnome-logo-text.svg as an example.
Fixes a deadlock where post-resume.target has After=post-resume.service
and post-resume.service runs systemctl try-restart post-resume.target
the systemctl call cannot complete if post-resume.target was already
queued at that time.
This reverts commit 05958b228b.
Issue https://github.com/NixOS/nixpkgs/issues/188998 is concerns quite a
few NixOS users with full disk encryption and custom keymap.
Since there hasn't been a proper fix agreed upon and merged, I am
reverting this.
The changes can be applied again, when it is ensured that they do not
break custom keymaps in initrd.
Prior to this change, ffmpeg couldn't be built for an
environment.noXlibs system, because it would fail in:
ffmpeg → SDL2 → libdecor
ffmpeg certainly does not need support for SDL2 windowing on a noXlibs
system.
This fix is important because the minidlna NixOS test, which uses the
minimal profile (and therefore environment.noXlibs) and ffmpeg, can't
currently build.
The primary difference between the standard and minimal variants of
this package is that all the X libraries are removed from the minimal
variant.
I had to switch the order of the definitions in all-packages.nix to
avoid an infinite recursion after the overlay was applied.
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.
this renders the same in the manpage and a little more clearly in the
html manual. in the manpage there continues to be no distinction from
regular text, the html manual gets code-type markup (which was probably
the intention for most of these uses anyway).
According to pulseaudio(1), a system wide pulseaudio instance
can only be accessed by members of the `pulse-access` group.
This name seems to be hardcoded in
pulseaudio -- I didn't find any switch to change it.
We need to define the group so users can connect to the deamon.
This commit also fixes the systemwide pulseaudio vm test:
Previously, the test user `alice`
was just a member of the `audio` group.
This blocked access to the daemon and failed the test.
The commit changes the group assignment and fixes the vm test.
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.
markdown can't represent the difference without another extension and
both the html manual and the manpage render them the same, so keeping the
distinction is not very useful on its own. with the distinction removed
we can automatically convert many options that use <code> tags to markdown.
the manpage remains unchanged, html manual does not render
differently (but class names on code tags do change from "code" to "literal").
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.
The suspend-then-hibernate functionality is implemented by systemd in
the suspend-then-hibernate.target, separately from suspend.target and
hibernate.target. Thus post-resume would not run after resuming from
suspend-then-hibernate.
Fix this by explicitly making post-resume run after
suspend-then-hibernate.
It was never meant to be used for anything other than testing
and setting it globally can cause weird loops in GTK-based portals,
where the portal will end up waiting for itself until it times out.

Or it can mess up fonts:

Having the option in NixOS makes it look like it is okay or even
desirable to enable, when in fact it is a hack that can subtly break apps.
Some apps allow opting into using portal-based APIs, e.g. for Firefox,
you can set `widget.use-xdg-desktop-portal.file-picker` to `1` in about:config.
Otherwise, you can set the `GTK_USE_PORTAL` environment variable to 1
for individual apps.
People who really want it and aware of the downsides can just set
`environment.sessionVariables.GTK_USE_PORTAL = "1";` NixOS option
directly to set the environment variable globally.
More nixpkgs code such as `boot.initrd.systemd.emergencyAccess` defines
options that takes hashed passwords, so move the type definition from
modules/ into lib/.
The type definition itself stays unchanged.
