Having the .tmp suffix is broken w.r.t. to multiple writers,
as they would overwrite existing files. using the atomic flag
will make write_file to create a unique temporary file it gets renamed
to its target.
This hook moves systemd user service file from `lib/systemd/user` to
`share/systemd/user`. This is to allow systemd to find the user
services when installed into a user profile. The `lib/systemd/user`
path does not work since `lib` is not in `XDG_DATA_DIRS`.
This fixes the case when Jack Audio Daemon is running
as a service via `services.jack.jackd` and Pulseaudio
running as a *user* service.
Two issues prevented connecting `pulse` with `jackd`:
* Missing `JACK_PROMISCUOUS_SERVER` environment variable for `pulse` user service,
resulting in `pulse` trying to access `jackd` as if it was running as part of
the users session.
* `jackd` not being able to access socket created by `pulse` due to socket
created using user ID and `users` group. Change allows `jackd` to access
the socket created by `pulse` correctly.
`pulse` now also autoloads `module-jack-sink` and `module-jack-source`
if `services.jack.jackd.enable` is set.
The default `pulse` package is now set to `pulseaudioFull` automatically
if `services.jack.jackd.enable` is set.

The incompatibility does not seem to exist any more: programs linked against fc 2.12
on fc 2.14 system seem to at least display text, even while printing tons of errors
(as long as you generate fc cache manually), and same thing the other way around.
Hopefully it will not be an issue in the future.
In some tests, e.g. -f nixos/release.nix tests.simple.x86_64-linux
we use noXlibs and qemu.ga. Now that output is tiny but to get it
a full qemu build is done, and some dependencies like gtk3 won't build
with noXlibs due to their dependencies being too stripped down.
Therefore let's reduce qemu features in noXlibs case.
The `sdlSupport = false;` part probably wasn't needed,
but I added it for consistency.
Turns out lot of software (including Chromium) use bundled fontconfig
so we either need to wrap every one of those, or re-introduce the global unversioned config.
The latter is easier but weakens hermetic configs. But perhaps those are not really worth the effort.
This allows disabling users.mutableUsers without configuring any
authentication mechanisms (passwords, authorized SSH keys) other than
Google OS Login.
This is required by (among others) Podman to run containers in rootless mode.
Other distributions such as Fedora and Ubuntu already set up these mappings.
The scheme with a start UID/GID offset starting at 100000 and increasing in 65536 increments is copied from Fedora.
Falling back to unversioned `/etc/fonts/conf.d` when versioned one does not exist
is problematic since it only occurs on non-NixOS systems and those are likely
to have a different version of fontconfig. When those versions use incompatible
elements in the config, apps using fontconfig will crash.
Instead, we are now falling back to the in-package `fonts.conf` file that loads
both the versioned global `conf.d` directory and the in-package `conf.d` since using
upstream settings on non-NixOS is preferable to not being able to use apps there.
In fact, we would not even need to link `fonts.conf`, as the in-package `fonts.conf`
will be always used unless someone creates the global one manually (the option is still
retained if one wants to write a custom NixOS module and to avoid unnecessary stat call on NixOS).
Additionally, since the `fonts.conf` will always load `conf.d` from the package, we no longer
need to install them to sytem `/etc` in the module. This needed some mucking with `50-user.conf`
which disables configs in user directories (a good thing IMO, NixOS module will turn it back on)
but otherwise, it is cleaner. The files are still prioritized by their name, regardless of their location.
See https://github.com/NixOS/nixpkgs/pull/73795#issuecomment-634370125 for more information.
This explanation was contained in the description of
security.initialRootPassword but got lost when it was deprecated
a long ago (f496c3c) and removed.
This option has been deprecated for a long time because is redundant
(users.users.root.initialHashedPassword exists).
Moreover, being of type string, it required to handle the special value
"!" separately, instead of using just `null`.
This explains the
# Allow the user to log in as root without a password.
users.users.root.initialHashedPassword = "";
that the NixOS installer live systems use in
`profiles/installation-device.nix`.
This fixes the output of "hostname --fqdn" (previously the domain name
was not appended). Additionally it's now possible to use the FQDN.
This works by unconditionally adding two entries to /etc/hosts:
127.0.0.1 localhost
::1 localhost
These are the first two entries and therefore gethostbyaddr() will
always resolve "127.0.0.1" and "::1" back to "localhost" [0].
This works because nscd (or rather the nss-files module) returns the
first matching row from /etc/hosts (and ignores the rest).
The FQDN and hostname entries are appended later to /etc/hosts, e.g.:
127.0.0.2 nixos-unstable.test.tld nixos-unstable
::1 nixos-unstable.test.tld nixos-unstable
Note: We use 127.0.0.2 here to follow nss-myhostname (systemd) as close
as possible. This has the advantage that 127.0.0.2 can be resolved back
to the FQDN but also the drawback that applications that only listen to
127.0.0.1 (and not additionally ::1) cannot be reached via the FQDN.
If you would like this to work you can use the following configuration:
```nix
networking.hosts."127.0.0.1" = [
"${config.networking.hostName}.${config.networking.domain}"
config.networking.hostName
];
```
Therefore gethostbyname() resolves "nixos-unstable" to the FQDN
(canonical name): "nixos-unstable.test.tld".
Advantages over the previous behaviour:
- The FQDN will now also be resolved correctly (the entry was missing).
- E.g. the command "hostname --fqdn" will now work as expected.
Drawbacks:
- Overrides entries form the DNS (an issue if e.g. $FQDN should resolve
to the public IP address instead of 127.0.0.1)
- Note: This was already partly an issue as there's an entry for
$HOSTNAME (without the domain part) that resolves to
127.0.1.1 (!= 127.0.0.1).
- Unknown (could potentially cause other unexpected issues, but special
care was taken).
[0]: Some applications do apparently depend on this behaviour (see
c578924) and this is typically the expected behaviour.

Instead of hardcoding all nss modules that are added into nsswitch,
there are now options exposed.
This allows users to add own nss modules (I had this issue with
winbindd, for example).
Also, nss modules could be moved to their NixOS modules which would
make the nsswitch module slimmer.
As the lists are now handled by the modules system, we can use mkOrder
to ensure a proper order as well as mkForce to override one specific
database type instead of the entire file.
This prevents duplication in cross-compiled nixos machines. The
bootstrapped glibc differs from the natively compiled one, so we get
two glibc’s in the closure. To reduce closure size, just use
stdenv.cc.libc where available.
When blocklists are built with a derivation, using extraHosts would
require IFD, since the result of the derivation needs to be converted to
a string again.
By introducing this option no IFD is needed for such use-cases, since
the fetched files can be assigned directly.
This commit changes the console colors implementation
to use the kernel parameters instead of relying on terminal
escape sequences. This means the palette is applied by the
kernel itself with no custom code running in the initrd
and works for all virtual terminals (not only tty0).
This commit moves all the virtual console related options
to a dedicated config/console.nix NixOS module.
Currently most of these are defined in config/i18n.nix
with a "console" prefix like `i18n.consoleFont`,
`i18n.consoleColors` or under `boot` and are implemented
in tasks/kbd.nix.
Since they have little to do with actual internationalisation
and are (informally) in an attrset already, it makes sense to
move them to a specific module.
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
This PR is part of the networking.* namespace cleanup. We feel that
networking.hostConf is rarely used and provides little value compared to
using environment.etc."host.conf" directly.
Provide sensible default: multi on
This is a more sane default since we do not magically (without opt-in)
pull in binaries from `~/bin`. That is not really an expected behavior
for many users. Users that still want that behavior can now just flip
that switch.
This PR is part of the networking.* namespace cleanup.
The Cisco VPN module is currently of limited value since it just creates
config files but does not manage services. The same functionality can be
achieved by using _environment.etc_ instead.
It would be a different situation if we had a full service module. So if
you are annoyed by this change, please consider write a more featureful
module and put its options unter _services.networking.vpnc_.
Note that this change removes options for *Cisco VPN*, not
*networkmanager-vpn*.
This fixes user environment setup for sessions which doesn't successfully go
through a shell init.
Note we don't go through `sessionVariables` as we want the wrappers to have
highest priority. It would also cause wrapperDir to occur twice when in shell
sessions, as shells use `sessionVariables` too while prepending wrapperDir in a
custom snippet.
In particular logging in and out of gnome-shell could result in a broken path
without this fix.
This enlarges the system uid/gid range 6-fold, from 100 to 600 ids. This
is a preventative measure against running out of dynamically allocated
ids for NixOS services with isSystemUser, which should become the
preferred way of allocating uids for non-real users.
We were only replacing them in the profiles. We also need to do this in
the values of variables, including both the session-relative variables
and the non-session-relative variables.
In fontconfig’s 60-generic.conf, order of preference is estabilished for emoji
font family. Because fontconfig parses the config files in lexicographic order,
appending each <prefer> from <alias> element to the family’s prefer list
(to be prepended before the family) [1], our font family defaults stored
in 52-nixos-default-fonts.conf will take precedence. That is, of course, unless
the default „weak“ binding [2] is used. Emoji family binds strongly [3],
so we need to set binding to “same” for our <alias>es to be considered before
the ones from 60-generic.conf.
By default, we will set the option to all emoji fonts supported by fontconfig,
so that emoji works for user if they have at least one emoji font installed.
If they have multiple emoji fonts installed, we will use the fontconfig’s
order of preference [4].

It currently lacks an emoji font-family which means it has to be
disabled for them to function [0]. Additionally it's fallen out of
necessity to ship custom font rendering settings (as far as I'm aware
of).

We don’t want any trailing whitespace, otherwise we mess up the
formating of the shadow file. Some things like readFile may have the
trailing new line.

This module correctly includes the vte.sh script
required for vte terminals like gnome-terminal to show the
CWD in the window title and preserved across instances.
This is achieved with the options:
* programs.bash.vteIntegration
* programs.zsh.vteIntegration
as it's best to keep this configuration unguarded by gnome3.enable
to support other vte terminals (such as elementary-terminal).
Note the distinction between Zsh and Bash doesn't include
a different script, as this script only supports those two shells.
systemd provides two sysctl snippets, 50-coredump.conf and
50-default.conf.
These enable:
- Loose reverse path filtering
- Source route filtering
- `fq_codel` as a packet scheduler (this helps to fight bufferbloat)
This also configures the kernel to pass coredumps to `systemd-coredump`.
These sysctl snippets can be found in `/etc/sysctl.d/50-*.conf`,
and overridden via `boot.kernel.sysctl`
(which will place the parameters in `/etc/sysctl.d/60-nixos.conf`.
Let's start using these, like other distros already do for quite some
time, and remove those duplicate `boot.kernel.sysctl` options we
previously did set.
In the case of rp_filter (which systemd would set to 2 (loose)), make
our overrides to "1" more explicit.
sysctl.d(5) recommends prefixing all filenames in /etc/sysctl.d with a
two-digit number and a dash, to simplify the ordering of the files.
Some packages provide custom files, often with "50-" prefix.
To ensure user-supplied configuration takes precedence over the one
specified via `boot.kernel.sysctl`, prefix the file generated there with
"60-".
