Release 18.09 ("Jellyfish", 2018/10/05)
Highlights
In addition to numerous new and upgraded packages, this release has the following notable updates:
-
End of support is planned for end of April 2019, handing over to 19.03.
-
Platform support: x86_64-linux and x86_64-darwin as always. Support for aarch64-linux is as with the previous releases, not equivalent to the x86-64-linux release, but with efforts to reach parity.
-
Nix has been updated to 2.1; see its release notes.
-
Core versions: linux: 4.14 LTS (unchanged), glibc: 2.26 → 2.27, gcc: 7 (unchanged), systemd: 237 → 239.
-
Desktop version changes: gnome: 3.26 → 3.28, (KDE) plasma-desktop: 5.12 → 5.13.
Notable changes and additions for 18.09 include:
-
Support for wrapping binaries using
firejail
has been added throughprograms.firejail.wrappedBinaries
.For example
{ programs.firejail = { enable = true; wrappedBinaries = { firefox = "${lib.getBin pkgs.firefox}/bin/firefox"; mpv = "${lib.getBin pkgs.mpv}/bin/mpv"; }; }; }
This will place
firefox
andmpv
binaries in the global path wrapped by firejail. -
User channels are now in the default
NIX_PATH
, allowing users to use their personalnix-channel
defined channels innix-build
andnix-shell
commands, as well as in imports likeimport <mychannel>
.For example
$ nix-channel --add https://nixos.org/channels/nixpkgs-unstable nixpkgsunstable $ nix-channel --update $ nix-build '<nixpkgsunstable>' -A gitFull $ nix run -f '<nixpkgsunstable>' gitFull $ nix-instantiate -E '(import <nixpkgsunstable> {}).gitFull'
New Services
A curated selection of new services that were added since the last release:
-
The
services.cassandra
module has been reworked and was rewritten from scratch. The service has succeeding tests for the versions 2.1, 2.2, 3.0 and 3.11 of Apache Cassandra. -
There is a new
services.foundationdb
module for deploying FoundationDB clusters. -
When enabled the
iproute2
will copy the files expected by ip route (e.g.,rt_tables
) in/etc/iproute2
. This allows to write aliases for routing tables for instance. -
services.strongswan-swanctl
is a modern replacement forservices.strongswan
. You can use either one of them to setup IPsec VPNs but not both at the same time.services.strongswan-swanctl
uses the swanctl command which uses the modern vici Versatile IKE Configuration Interface. The deprecatedipsec
command used inservices.strongswan
is using the legacy stroke configuration interface. -
The new
services.elasticsearch-curator
service periodically curates or manages, your Elasticsearch indices and snapshots.

-
The deprecated
services.cassandra
module has seen a complete rewrite. (See above.) -
lib.strict
is removed. Usebuiltins.seq
instead. -
The
clementine
package points now to the free derivation.clementineFree
is removed now andclementineUnfree
points to the package which is bundled with the unfreelibspotify
package. -
The
netcat
package is now taken directly from OpenBSD'slibressl
, instead of relying on Debian's fork. The new version should be very close to the old version, but there are some minor differences. Importantly, flags like -b, -q, -C, and -Z are no longer accepted by the nc command. -
The
services.docker-registry.extraConfig
object doesn't contain environment variables anymore. Instead it needs to provide an object structure that can be mapped onto the YAML configuration defined in thedocker/distribution
docs. -
gnucash
has changed from version 2.4 to 3.x. If you've been usinggnucash
(version 2.4) instead ofgnucash26
(version 2.6) you must open your Gnucash data file(s) withgnucash26
and then save them to upgrade the file format. Then you may use your data file(s) with Gnucash 3.x. See the upgrade documentation. Gnucash 2.4 is still available under the attributegnucash24
. -
services.munge
now runs as user (and group)munge
instead of root. Make sure the key file is accessible to the daemon. -
dockerTools.buildImage
now usesnull
as default value fortag
, which indicates that the nix output hash will be used as tag. -
The ELK stack:
elasticsearch
,logstash
andkibana
has been upgraded from 2.* to 6.3.*. The 2.* versions have been unsupported since last year so they have been removed. You can still use the 5.* versions under the nameselasticsearch5
,logstash5
andkibana5
.The elastic beats:
filebeat
,heartbeat
,metricbeat
andpacketbeat
have had the same treatment: they now target 6.3.* as well. The 5.* versions are available under the names:filebeat5
,heartbeat5
,metricbeat5
andpacketbeat5
The ELK-6.3 stack now comes with X-Pack by default. Since X-Pack is licensed under the Elastic License the ELK packages now have an unfree license. To use them you need to specify
allowUnfree = true;
in your nixpkgs configuration.Fortunately there is also a free variant of the ELK stack without X-Pack. The packages are available under the names:
elasticsearch-oss
,logstash-oss
andkibana-oss
. -
Options
boot.initrd.luks.devices.name.yubikey.ramfsMountPoint
boot.initrd.luks.devices.name.yubikey.storage.mountPoint
were removed.luksroot.nix
module never supported more than one YubiKey at a time anyway, hence those options never had any effect. You should be able to remove them from your config without any issues. -
stdenv.system
andsystem
in nixpkgs now refer to the host platform instead of the build platform. For native builds this is not change, let alone a breaking one. For cross builds, it is a breaking change, andstdenv.buildPlatform.system
can be used instead for the old behavior. They should be using that anyways for clarity. -
Groups
kvm
andrender
are introduced now, as systemd requires them.
Other Notable Changes
-
dockerTools.pullImage
relies on image digest instead of image tag to download the image. Thesha256
of a pulled image has to be updated. -
lib.attrNamesToStr
has been deprecated. Use more specific concatenation (lib.concat(Map)StringsSep
) instead. -
lib.addErrorContextToAttrs
has been deprecated. Usebuiltins.addErrorContext
directly. -
lib.showVal
has been deprecated. Uselib.traceSeqN
instead. -
lib.traceXMLVal
has been deprecated. Uselib.traceValFn builtins.toXml
instead. -
lib.traceXMLValMarked
has been deprecated. Uselib.traceValFn (x: str + builtins.toXML x)
instead. -
The
pkgs
argument to NixOS modules can now be set directly usingnixpkgs.pkgs
. Previously, only thesystem
,config
andoverlays
arguments could be used to influencepkgs
. -
A NixOS system can now be constructed more easily based on a preexisting invocation of Nixpkgs. For example:
{ inherit (pkgs.nixos { boot.loader.grub.enable = false; fileSystems."/".device = "/dev/xvda1"; }) toplevel kernel initialRamdisk manual; }
This benefits evaluation performance, lets you write Nixpkgs packages that depend on NixOS images and is consistent with a deployment architecture that would be centered around Nixpkgs overlays.
-
lib.traceValIfNot
has been deprecated. Useif/then/else
andlib.traceValSeq
instead. -
lib.traceCallXml
has been deprecated. Please complain if you use the function regularly. -
The attribute
lib.nixpkgsVersion
has been deprecated in favor oflib.version
. Please refer to the discussion in NixOS/nixpkgs#39416 for further reference. -
lib.recursiveUpdateUntil
was not acting according to its specification. It has been fixed to act according to the docstring, and a test has been added. -
The module for
security.dhparams
has two new options now:security.dhparams.stateless
-
Puts the generated Diffie-Hellman parameters into the Nix store instead of managing them in a stateful manner in
/var/lib/dhparams
. security.dhparams.defaultBitSize
-
The default bit size to use for the generated Diffie-Hellman parameters.
::: {.note} The path to the actual generated parameter files should now be queried using
config.security.dhparams.params.name.path
because it might be either in the Nix store or in a directory configured bysecurity.dhparams.path
. :::::: {.note} For developers:
Module implementers should not set a specific bit size in order to let users configure it by themselves if they want to have a different bit size than the default (2048).
An example usage of this would be:
{ config, ... }: { security.dhparams.params.myservice = {}; environment.etc."myservice.conf".text = '' dhparams = ${config.security.dhparams.params.myservice.path} ''; }
:::
-
networking.networkmanager.useDnsmasq
has been deprecated. Usenetworking.networkmanager.dns
instead. -
The Kubernetes package has been bumped to major version 1.11. Please consult the release notes for details on new features and api changes.
-
The option
services.kubernetes.apiserver.admissionControl
was renamed toservices.kubernetes.apiserver.enableAdmissionPlugins
. -
Recommended way to access the Kubernetes Dashboard is via HTTPS (TLS) Therefore; public service port for the dashboard has changed to 443 (container port 8443) and scheme to https.
-
The option
services.kubernetes.apiserver.address
was renamed toservices.kubernetes.apiserver.bindAddress
. Note that the default value has changed from 127.0.0.1 to 0.0.0.0. -
The option
services.kubernetes.apiserver.publicAddress
was not used and thus has been removed. -
The option
services.kubernetes.addons.dashboard.enableRBAC
was renamed toservices.kubernetes.addons.dashboard.rbac.enable
. -
The Kubernetes Dashboard now has only minimal RBAC permissions by default. If dashboard cluster-admin rights are desired, set
services.kubernetes.addons.dashboard.rbac.clusterAdmin
to true. On existing clusters, in order for the revocation of privileges to take effect, the current ClusterRoleBinding for kubernetes-dashboard must be manually removed:kubectl delete clusterrolebinding kubernetes-dashboard
-
The
programs.screen
module provides allows to configure/etc/screenrc
, however the module behaved fairly counterintuitive as the config exists, but the package wasn't available. Since 18.09pkgs.screen
will be added toenvironment.systemPackages
. -
The module
services.networking.hostapd
now uses WPA2 by default. -
s6Dns
,s6Networking
,s6LinuxUtils
ands6PortableUtils
renamed tos6-dns
,s6-networking
,s6-linux-utils
ands6-portable-utils
respectively. -
The module option
nix.useSandbox
is now defaulted totrue
. -
The config activation script of
nixos-rebuild
now reloads all user units for each authenticated user. -
The default display manager is now LightDM. To use SLiM set
services.xserver.displayManager.slim.enable
totrue
. -
NixOS option descriptions are now automatically broken up into individual paragraphs if the text contains two consecutive newlines, so it's no longer necessary to use
</para><para>
to start a new paragraph. -
Top-level
buildPlatform
,hostPlatform
, andtargetPlatform
in Nixpkgs are deprecated. Please use their equivalents instdenv
instead:stdenv.buildPlatform
,stdenv.hostPlatform
, andstdenv.targetPlatform
.
