Release 22.11 (“Raccoon”, 2022.11/??)
Support is planned until the end of June 2023, handing over to 23.05.
Highlights
In addition to numerous new and upgraded packages, this release has the following highlights:
-
GNOME has been upgraded to 43. Please take a look at their Release Notes for details.
-
During cross-compilation, tests are now executed if the test suite can be executed by the build platform. This is the case when doing “native” cross-compilation where the build and host platforms are largely the same, but the nixpkgs' cross compilation infrastructure is used, e.g.
pkgsStatic
andpkgsLLVM
. Another possibility is that the build platform is a superset of the host platform, e.g. when cross-compiling fromx86_64-unknown-linux
toi686-unknown-linux
. The predicate gating test suite execution is the newly addedcanExecute
predicate: You can e.g. check ifstdenv.buildPlatform
can execute binaries built forstdenv.hostPlatform
(i.e. produced bystdenv.cc
) by evaluatingstdenv.buildPlatform.canExecute stdenv.hostPlatform
. -
The
nixpkgs.hostPlatform
andnixpkgs.buildPlatform
options have been added. These cover and override thenixpkgs.{system,localSystem,crossSystem}
options.hostPlatform
is the platform or "system
" string of the NixOS system described by the configuration.buildPlatform
is the platform that is responsible for building the NixOS configuration. It defaults to thehostPlatform
, for a non-cross build configuration. To cross compile, setbuildPlatform
to a different value.
The new options convey the same information, but with fewer options, and following the Nixpkgs terminology.
The existing options
nixpkgs.{system,localSystem,crossSystem}
have not been formally deprecated, to allow for evaluation of the change and to allow for a transition period so that in time the ecosystem can switch without breaking compatibility with any supported NixOS release. -
emacs
enables native compilation which means:- emacs packages from nixpkgs, builtin or not, will do native compilation ahead of time so you can enjoy the benefit of native compilation without compiling them on you machine;
- emacs packages from somewhere else, e.g.
package-install
, will do asynchronously deferred native compilation. If you do not want this, maybe to avoid CPU consumption for compilation, you can use(setq native-comp-deferred-compilation nil)
to disable it while still enjoy the benefit of native compilation for packages from nixpkgs.
-
nixos-generate-config
now generates configurations that can be built in pure mode. This is achieved by setting the newnixpkgs.hostPlatform
option.You may have to unset the
system
parameter inlib.nixosSystem
, or similarly remove definitions of thenixpkgs.{system,localSystem,crossSystem}
options.Alternatively, you can remove the
hostPlatform
line and use NixOS like you would in NixOS 22.05 and earlier. -
PHP now defaults to PHP 8.1, updated from 8.0.
-
PHP is now built
NTS
(Non-Thread Safe) style by default, for Apache andmod_php
usage we still enableZTS
(Zend Thread Safe). This has been a common practice for a long time in other distributions. -
PHP 8.2.0 RC 6 is available.
-
protonup
has been aliased to and replaced byprotonup-ng
due to upstream not maintaining it. -
Perl has been updated to 5.36, and its core module
HTTP::Tiny
was patched to verify SSL/TLS certificates by default. -
Improved performances of
lib.closePropagation
which was previously quadratic. This is used in e.g.ghcWithPackages
. Please see backward incompatibilities notes below. -
Cinnamon has been updated to 5.4. While at it, the cinnamon module now defaults to blueman as bluetooth manager and slick-greeter as lightdm greeter to match upstream.
-
OpenSSL now defaults to OpenSSL 3, updated from 1.1.1.
-
An image configuration and generator has been added for Linode images, largely based on the present GCE configuration and image.
-
hardware.nvidia
has a new optionopen
that can be used to opt in the opensource version of NVIDIA kernel driver. Note that the driver's support for GeForce and Workstation GPUs is still alpha quality, see NVIDIA Releases Open-Source GPU Kernel Modules for the official announcement.

Backward Incompatibilities
-
Nixpkgs now requires Nix 2.3 or newer.
-
The
isCompatible
predicate checking CPU compatibility is no longer exposed by the platform sets generated usinglib.systems.elaborate
. In most cases you will want to use the newcanExecute
predicate instead which also considers the kernel / syscall interface. It is briefly described in the release's highlights section.lib.systems.parse.isCompatible
still exists, but has changed semantically: Architectures with differing endianness modes are no longer considered compatible. -
ngrok
has been upgraded from 2.3.40 to 3.0.4. Please see the upgrade guide and changelog. Notably, breaking changes are that the config file format has changed and support for single hypen arguments was dropped. -
i18n.supportedLocales
is now by default only generated with the locales set ini18n.defaultLocale
andi18n.extraLocaleSettings
. This got partially copied over from the minimal profile and reduces the final system size by up to 200MB. If you require all locales installed set the option to[ "all" ]
. -
Deprecated settings
logrotate.paths
andlogrotate.extraConfig
have been removed. Please convert any uses to services.logrotate.settings instead. -
The
isPowerPC
predicate, found onplatform
attrsets (hostPlatform
,buildPlatform
,targetPlatform
, etc) has been removed in order to reduce confusion. The predicate was was defined such that it matches only the 32-bit big-endian members of the POWER/PowerPC family, despite having a name which would imply a broader set of systems. If you were using this predicate, you can replacefoo.isPowerPC
with(with foo; isPower && is32bit && isBigEndian)
. -
The
fetchgit
fetcher now uses cone mode by default for sparse checkouts. Non-cone mode can be enabled by passingnonConeMode = true
, but note that non-cone mode is deprecated and this option may be removed alongside a future Git update without notice. -
openssh
was updated to version 9.1, disabling the generation of DSA keys when usingssh-keygen -A
as they are insecure. Also,SetEnv
directives inssh_config
andsshd_config
are now first-match-wins -
bsp-layout
no longer uses the commandcycle
to switch to other window layouts, as it got replaced by the commandsprevious
andnext
. -
The Barco ClickShare driver/client package
pkgs.clickshare-csc1
and the optionprograms.clickshare-csc1.enable
have been removed, as it requiresqt4
, which reached its end-of-life 2015 and will no longer be supported by nixpkgs. According to Barco many of their base unit models can be used with Google Chrome and the Google Cast extension. -
services.hbase
has been renamed toservices.hbase-standalone
. For production HBase clusters, useservices.hadoop.hbase
instead. -
The
p4
package now only includes the open-source Perforce Helix Core command-line client and APIs. It no longer installs the unfree Helix Core Server binariesp4d
,p4broker
, andp4p
. To install the Helix Core Server binaries, use thep4d
package instead. -
The
openssl
-extension for the PHP interpreter used by Nextcloud is built against OpenSSL 1.1 if is below22.11
. This is to make sure that people using server-side encryption don't loose access to their files.In any other case it's safe to use OpenSSL 3 for PHP's openssl extension. This can be done by setting to
false
. -
The
coq
package and versioned variants starting atcoq_8_14
no longer include CoqIDE, which is now available throughcoqPackages.coqide
. It is still possible to get CoqIDE as part of thecoq
package by overriding thebuildIde
argument of the derivation. -
PHP 7.4 is no longer supported due to upstream not supporting this version for the entire lifecycle of the 22.11 release.
-
The ipfs package and module were renamed to kubo. The kubo module now uses an RFC42-style
settings
option instead ofextraConfig
and thegatewayAddress
,apiAddress
andswarmAddress
options were renamed. Using the old names will print a warning but still work. -
pkgs.cosign
does not provide thecosigned
binary anymore. Thesget
binary has been moved into its own package. -
Emacs now uses the Lucid toolkit by default instead of GTK because of stability and compatibility issues. Users who still wish to remain using GTK can do so by using
emacs-gtk
. -
riak package removed along with
services.riak
module, due to lack of maintainer to update the package. -
ppd files in
pkgs.cups-drv-rastertosag-gdi
are now gzipped. If you refer to such a ppd file with its path (e.g. via hardware.printers.ensurePrinters) you will need to append.gz
to the path. -
xow package removed along with the
hardware.xow
module, due to the project being deprecated in favor ofxone
, which is available via thehardware.xone
module. -
dd-agent package removed along with the
services.dd-agent
module, due to the project being deprecated in favor ofdatadog-agent
, which is available via theservices.datadog-agent
module. -
teleport
has been upgraded to major version 10. Please see upstream upgrade instructions and release notes. -
lib.closePropagation
now needs that all gathered sets have anoutPath
attribute. -
lemmy module option
services.lemmy.settings.database.createLocally
moved toservices.lemmy.database.createLocally
. -
virtlyst package and
services.virtlyst
module removed, due to lack of maintainers. -
The
nix.checkConfig
option now fully disables the config check. The newnix.checkAllErrors
option behaves likenix.checkConfig
previously did. -
generateOptparseApplicativeCompletions
andgenerateOptparseApplicativeCompletion
fromhaskell.lib.compose
(andhaskell.lib
) have been deprecated in favor ofgenerateOptparseApplicativeCompletions
(plural!) as provided by the haskell package sets (sohaskellPackages.generateOptparseApplicativeCompletions
etc.). The latter allows for cross-compilation (by automatically disabling generation of completion in the cross case). For it to work properly you need to make sure that the function comes from the same context as the package you are trying to override, i.e. always use the same package set as your package is coming from or – even better – useself.generateOptparseApplicativeCompletions
if you are overriding a haskell package set. The old functions are retained for backwards compatibility, but yield are warning. -
The
services.graphite.api
andservices.graphite.beacon
NixOS options, and thepython3.pkgs.graphite_api
,python3.pkgs.graphite_beacon
andpython3.pkgs.influxgraph
packages, have been removed due to lack of upstream maintenance. -
The
trace
binary fromperf-linux
package has been removed, due to being a duplicate of theperf
binary. -
The
aws
package has been removed due to being abandoned by the upstream. It is recommended to useawscli
orawscli2
instead. -
The CEmu TI-84 Plus CE emulator package has been renamed to
cemu-ti
. The Cemu Wii U emulator is now packaged ascemu
. -
systemd-networkd
v250 deprecated, renamed, and moved some sections and settings which leads to the following breaking module changes:systemd.network.networks.<name>.dhcpV6PrefixDelegationConfig
is renamed tosystemd.network.networks.<name>.dhcpPrefixDelegationConfig
.systemd.network.networks.<name>.dhcpV6Config
no longer accepts theForceDHCPv6PDOtherInformation=
setting. Please use theWithoutRA=
andUseDelegatedPrefix=
settings in yoursystemd.network.networks.<name>.dhcpV6Config
and theDHCPv6Client=
setting in yoursystemd.network.networks.<name>.ipv6AcceptRAConfig
to control when the DHCPv6 client is started and how the delegated prefixes are handled by the DHCPv6 client.systemd.network.networks.<name>.networkConfig
no longer accepts theIPv6Token=
setting. Use theToken=
setting in yoursystemd.network.networks.<name>.ipv6AcceptRAConfig
instead. Thesystemd.network.networks.<name>.ipv6Prefixes.*.ipv6PrefixConfig
now also accepts theToken=
setting.
-
arangodb
versions 3.3, 3.4, and 3.5 have been removed because they are at EOL upstream. The default is now 3.10.0. Support for aarch64-linux has been removed since the target cannot be built reproducibly. By defaultarangodb
is now built for thehaswell
architecture. If you wish to build for a different architecture, you may override thetargetArchitecture
argument with a value from this list supported upstream. Some architecture specific optimizations are also conditionally enabled. You may alter this behavior by overriding theasmOptimizations
parameter. You may also add additional architecture support by adding more-DHAS_XYZ
flags tocmakeFlags
viaoverrideAttrs
. -
The
meta.mainProgram
attribute of packages inwineWowPackages
now defaults to"wine64"
. -
The
paperless
module now defaultsPAPERLESS_TIME_ZONE
to your configured system timezone. -
The top-level
termonad-with-packages
alias fortermonad
has been removed. -
Linux 4.9 has been removed because it will reach its end of life within the lifespan of 22.11.
-
(Neo)Vim can not be configured with
configure.pathogen
anymore to reduce maintainance burden. Useconfigure.packages
instead. -
Neovim can not be configured with plug anymore (still works for vim).
-
The
adguardhome
module no longer useshost
andport
options, usesettings.bind_host
andsettings.bind_port
instead. -
The default
kops
version is now 1.25.1 and support for 1.22 and older has been dropped. -
The
zrepl
package has been updated from 0.5.0 to 0.6.0. See the changelog for details. -
k3s
no longer supports docker as runtime due to upstream dropping support. -
cassandra_2_1
andcassandra_2_2
have been removed. Please update tocassandra_3_11
orcassandra_3_0
. See the changelog for more information about the upgrade process. -
mysql57
has been removed. Please update tomysql80
ormariadb
. See the upgrade guide for more information. -
Consequently,
cqrlog
andamorok
now usemariadb
instead ofmysql57
for their embedded databases. Runningmysql_upgrade
may be neccesary. -
k3s
supportsclusterInit
option, and it is enabled by default, for servers. -
percona-server56
has been removed. Please migrate tomysql
ormariadb
if possible. -
obs-studio
hase been updated to version 28. If you have packaged custom plugins, check if they are compatible.obs-websocket
has been integrated intoobs-studio
. -
signald
has been bumped to0.23.0
. For the upgrade, a migration process is necessary. It can be done by running a command like this before startingsignald.service
:signald -d /var/lib/signald/db \ --database sqlite:/var/lib/signald/db \ --migrate-data
For further information, please read the upstream changelogs.
-
stylua
no longer acceptslua52Support
andluauSupport
overrides, usefeatures
instead, which defaults to[ "lua54" "luau" ]
. -
ocamlPackages.ocaml_extlib
has been renamed toocamlPackages.extlib
. -
pkgs.fetchNextcloudApp
has been rewritten to circumvent impurities in e.g. tarballs from GitHub and to make it easier to apply patches. This means that your hashes are out-of-date and the (previously required) attributesname
andversion
are no longer accepted. -
The Syncthing service now only allows absolute paths---starting with
/
or~/
---forservices.syncthing.folders.<name>.path
. In a future release other paths will be allowed again and interpreted relative toservices.syncthing.dataDir
. -
services.github-runner
andservices.github-runners.<name>
gained the optionserviceOverrides
which allows overriding the systemdserviceConfig
. If you have been overriding the systemd service configuration (i.e., by definingsystemd.services.github-runner.serviceConfig
), you have to use theserviceOverrides
option now. Example:services.github-runner.serviceOverrides.SupplementaryGroups = [ "docker" ];
Other Notable Changes
-
firefox
,thunderbird
andlibrewolf
come with enabled Wayland support by default. Thefirefox-wayland
,firefox-esr-wayland
,thunderbird-wayland
andlibrewolf-wayland
attributes are obsolete and have been aliased to their generic attribute. -
The
xplr
package has been updated from 0.18.0 to 0.19.0, which brings some breaking changes. See the upstream release notes for more details. -
Configuring multiple GitHub runners is now possible through
services.github-runners.<name>
. The optionservices.github-runner
remains. -
github-runner
gained support for ephemeral runners and registrations using a personal access token (PAT) instead of a registration token. Seeservices.github-runner.ephemeral
andservices.github-runner.tokenFile
for details. -
A new module was added for the Saleae Logic device family, providing the options
hardware.saleae-logic.enable
andhardware.saleae-logic.package
. -
ZFS module will not allow hibernation by default, this is a safety measure to prevent data loss cases like the ones described at OpenZFS/260 and OpenZFS/12842. Use the
boot.zfs.allowHibernation
option to configure this behaviour. -
mastodon
now automatically removes remote media attachments older than 30 days. This is configurable throughservices.mastodon.mediaAutoRemove
. -
The Redis module now disables RDB persistence when
services.redis.servers.<name>.save = []
instead of using the Redis default. -
Neo4j was updated from version 3 to version 4. See this migration guide on how to migrate your Neo4j instance.
-
The
networking.wireguard
module now can set the mtu on interfaces and tag its packets with an fwmark. -
The option
overrideStrategy
was added to the different systemd unit options (systemd.services.<name>
,systemd.sockets.<name>
, …) to allow enforcing the creation of a dropin file, rather than the main unit file, by setting it toasDropin
. This is useful in cases where the existence of the main unit file is not known to Nix at evaluation time, for example when the main unit file is provided by adding a package tosystemd.packages
. See the fix proposed in NixOS's systemd abstraction doesn't work with systemd template units for an example. -
The
polymc
package has been removed due to a rogue maintainer. It has been replaced byprismlauncher
, a fork by the rest of the maintainers. For more details, see the pull request that made this change and this issue detailing the vulnerability. Users with existing installations should rename~/.local/share/polymc
to~/.local/share/PrismLauncher
. The main config file's path has also moved from~/.local/share/polymc/polymc.cfg
to~/.local/share/PrismLauncher/prismlauncher.cfg
. -
The
bloat
package has been updated from unstable-2022-03-31 to unstable-2022-10-25, which brings a breaking change. See this upstream commit message for details. -
The
services.matrix-synapse
systemd unit has been hardened. -
The module
services.grafana
was refactored to be compliant with RFC 0042. To be precise, this means that the following things have changed:-
The newly introduced option is an attribute-set that will be converted into Grafana's INI format. This means that the configuration from Grafana's configuration reference can be directly written as attribute-set in Nix within this option.
-
The option
services.grafana.extraOptions
has been removed. This option was an association of environment variables for Grafana. If you had an expression like{ services.grafana.extraOptions.SECURITY_ADMIN_USER = "foobar"; }
your Grafana instance was running with
GF_SECURITY_ADMIN_USER=foobar
in its environment.For the migration, it is recommended to turn it into the INI format, i.e. to declare
{ services.grafana.settings.security.admin_user = "foobar"; }
instead.
The keys in
services.grafana.extraOptions
have the format<INI section name>_<Key Name>
. Further details are outlined in the configuration reference.Alternatively you can also set all your values from
extraOptions
tosystemd.services.grafana.environment
, make sure you don't forget to add theGF_
prefix though! -
Previously, the options and expected lists of datasources or dashboards for the declarative provisioning.
To declare lists of
This change was made to support more features for that:
-
It's possible to declare the
apiVersion
of your dashboards and datasources by (or ). -
Instead of declaring datasources and dashboards in pure Nix, it's also possible to specify configuration files (or directories) with YAML instead using (or . This is useful when having provisioning files from non-NixOS Grafana instances that you also want to deploy to NixOS.
Note: secrets from these files will be leaked into the store unless you use a file-provider or env-var for secrets!
-
is not affected by this change because this feature is deprecated by Grafana and will probably removed in Grafana 10. It's recommended to use
services.grafana.provision.alerting.contactPoints
instead.
-
-
-
The
services.grafana.provision.alerting
option was added. It includes suboptions for every alerting-related objects (with the exception ofnotifiers
), which means it's now possible to configure modern Grafana alerting declaratively. -
Matrix Synapse now requires entries in the
state_group_edges
table to be unique, in order to prevent accidentally introducing duplicate information (for example, because a database backup was restored multiple times). If your Synapse database already has duplicate rows in this table, this could fail with an error and require manual remediation. -
The
diamond
package has been update from 0.8.36 to 2.0.15. See the upstream release notes for more details. -
The
guake
package has been updated from 3.6.3 to 3.9.0, see the changelog for more details. -
dockerTools.buildImage
deprecates the misunderstoodcontents
parameter, in favor ofcopyToRoot
. UsecopyToRoot = buildEnv { ... };
or similar if you intend to add packages to/bin
. -
memtest86+ was updated from 5.00-coreboot-002 to 6.00-beta2. It is now the upstream version from https://www.memtest.org/, as coreboot's fork is no longer available.
-
Option descriptions, examples, and defaults writting in DocBook are now deprecated. Using CommonMark is preferred and will become the default in a future release.
-
The
documentation.nixos.options.allowDocBook
option was added to ease the transition to CommonMark option documentation. Setting this option tofalse
causes an error for every option included in the manual that uses DocBook documentation; it defaults totrue
to preserve the previous behavior and will be removed once the transition to CommonMark is complete. -
The redis module now persists each instance's configuration file in the state directory, in order to support some more advanced use cases like sentinel.
-
The udisks2 service, available at
services.udisks2.enable
, is now disabled by default. It will automatically be enabled through services and desktop environments as needed. This also means that polkit will now actually be disabled by default. The default forsecurity.polkit.enable
was already flipped in the previous release, but udisks2 being enabled by default re-enabled it. -
Nextcloud has been updated to version 25. Additionally the following things have changed for Nextcloud in NixOS:
- For Nextcloud >=24, the default PHP version is 8.1.
- Nextcloud 23 has been removed since it will reach its end of life in December 2022.
- For
system.stateVersion
being >=22.11, Nextcloud 25 will be installed by default. For older versions, Nextcloud 24 will be installed. - Please ensure that you only upgrade on major release at a time! Nextcloud doesn't support upgrades across multiple versions, i.e. an upgrade from 23 to 25 is only possible when upgrading to 24 first.
-
Add udev rules for the Teensy family of microcontrollers.
-
The Qt QML disk cache is now disabled by default. This fixes a long-standing issue where updating Qt/KDE apps would sometimes cause them to crash or behave strangely without explanation. Those concerned about the small (~10%) performance hit to application startup can re-enable the cache (and expose themselves to gremlins) by setting the envrionment variable
QML_FORCE_DISK_CACHE
to1
using e.g. theenvironment.sessionVariables
NixOS option. -
systemd-oomd is enabled by default. Depending on which systemd units have
ManagedOOMSwap=kill
orManagedOOMMemoryPressure=kill
, systemd-oomd will SIGKILL all the processes under the appropriate descendant cgroups when the configured limits are exceeded. NixOS does currently not configure cgroups with oomd by default, this can be enabled using systemd.oomd.enableRootSlice, systemd.oomd.enableSystemSlice, and systemd.oomd.enableUserServices. -
The
tt-rss
service performs two database migrations when you first use its web UI after upgrade. Consider backing up its database before updating. -
The
pass-secret-service
package now includes systemd units from upstream, so adding it to the NixOSservices.dbus.packages
option will make it start automatically as a systemd user service when an application tries to talk to the libsecret D-Bus API. -
There is a new module for AMD SEV CPU functionality, which grants access to the hardware.
-
The Wordpress module got support for installing language packs through
services.wordpress.sites.<site>.languages
. -
The default package for
services.mullvad-vpn.package
was changed topkgs.mullvad
, allowing cross-platform usage of Mullvad.pkgs.mullvad
only contains the Mullvad CLI tool, so users who rely on the Mullvad GUI will want to change it back topkgs.mullvad-vpn
, or addpkgs.mullvad-vpn
to their environment. -
PowerDNS has been updated from
4.6.x
to4.7.x
. Please be sure to review the Upgrade Notes provided by upstream before upgrading. Worth specifically noting is that the new Catalog Zones feature comes with a mandatory schema change for the gsql database backends, which has to be manually applied. -
There is a new module for the
thunar
program (the Xfce file manager), which depends on thexfconf
