Release 19.09 (“Loris”, 2019/09/??)Highlights
In addition to numerous new and upgraded packages, this release has the
following highlights:
End of support is planned for end of April 2020, handing over to 20.03.
PHP now defaults to PHP 7.3, updated from 7.2.
PHP 7.1 is no longer supported due to upstream not supporting this version for the entire lifecycle of the 19.09 release.
The binfmt module is now easier to use. Additional systems can
be added through .
For instance, boot.binfmt.emulatedSystems = [
"wasm32-wasi" "x86_64-windows" "aarch64-linux" ]; will
set up binfmt interpreters for each of those listed systems.
The installer now uses a less privileged nixos user whereas before we logged in as root.
To gain root privileges use sudo -i without a password.
New Services
The following new services were added since the last release:
./programs/dwm-status.nixBackward Incompatibilities
When upgrading from a previous release, please be aware of the following
incompatible changes:
Buildbot no longer supports Python 2, as support was dropped upstream in
version 2.0.0. Configurations may need to be modified to make them
compatible with Python 3.
PostgreSQL now uses
/run/postgresql as its socket
directory instead of /tmp. So
if you run an application like eg. Nextcloud, where you need to use
the Unix socket path as the database host name, you need to change it
accordingly.
The options and
have been removed
because the alertmanager service is now using systemd's
DynamicUser mechanism which obviates these options.
The NetworkManager systemd unit was renamed back from network-manager.service to
NetworkManager.service for better compatibility with other applications expecting this name.
The same applies to ModemManager where modem-manager.service is now called ModemManager.service again.
The and
options were removed as they are managed internally by the nzbget. The
option hadn't actually been used by
the module for some time and so was removed as cleanup.
The option was removed, as it was only used by the wordpress
apache-httpd service to wait for mysql to have started up.
This can be accomplished by either describing a dependency on mysql.service (preferred)
or waiting for the (hardcoded) /run/mysqld/mysql.sock file to appear.
The module has been removed, see
instead for a free software fork of Emby.
See the Jellyfin documentation:
Migrating from Emby to Jellyfin
IPv6 Privacy Extensions are now enabled by default for undeclared
interfaces. The previous behaviour was quite misleading — even though
the default value for
was
true, undeclared interfaces would not prefer temporary
addresses. Now, interfaces not mentioned in the config will prefer
temporary addresses. EUI64 addresses can still be set as preferred by
explicitly setting the option to false for the
interface in question.
Since Bittorrent Sync was superseded by Resilio Sync in 2016, the
bittorrentSync, bittorrentSync14,
and bittorrentSync16 packages have been removed in
favor of resilio-sync.
The corresponding module, has been
replaced by the module.
The httpd service no longer attempts to start the postgresql service. If you have come to depend
on this behaviour then you can preserve the behavior with the following configuration:
systemd.services.httpd.after = [ "postgresql.service" ];
The option has been
marked as deprecated. You may still use this feature, but it will be
removed in a future release of NixOS. You are encouraged to convert any
httpd subservices you may have written to a full NixOS module.
Most of the httpd subservices packaged with NixOS have been replaced with
full NixOS modules including LimeSurvey, WordPress, and Zabbix. These
modules can be enabled using the ,
, ,
and options.
The option
was renamed to
(capital L). This follows
upstreams renaming
of the setting.
As of this release the NixOps feature autoLuks is deprecated. It no longer works
with our systemd version without manual intervention.
Whenever the usage of the module is detected the evaluation will fail with a message
explaining why and how to deal with the situation.
A new knob named nixops.enableDeprecatedAutoLuks
has been introduced to disable the eval failure and to acknowledge the notice was received and read.
If you plan on using the feature please note that it might break with subsequent updates.
Make sure you set the _netdev option for each of the file systems referring to block
devices provided by the autoLuks module. Not doing this might render the system in a
state where it doesn't boot anymore.
If you are actively using the autoLuks module please let us know in
issue #62211.
The setopt declarations will be evaluated at the end of /etc/zshrc, so any code in ,
and may break if it relies on those options being set.
The prometheus-nginx-exporter package now uses the offical exporter provided by NGINX Inc.
Its metrics are differently structured and are incompatible to the old ones. For information about the metrics,
have a look at the official repo.
Nodejs 8 is scheduled EOL under the lifetime of 19.09 and has been dropped.
By default, prometheus exporters are now run with DynamicUser enabled.
Exporters that need a real user, now run under a seperate user and group which follow the pattern <exporter-name>-exporter, instead of the previous default nobody and nogroup.
Only some exporters are affected by the latter, namely the exporters dovecot, node, postfix and varnish.
The ibus-qt package is not installed by default anymore when is set to ibus.
If IBus support in Qt 4.x applications is required, add the ibus-qt package to your manually.
The CUPS Printing service now uses socket-based activation by
default, only starting when needed. The previous behavior can
be restored by setting
to
false.
Other Notable Changes
The module gained an option named
which makes the
generated configuration.nix5 manual page include all options
from all NixOS modules included in a given
configuration.nix configuration file. Currently, it is
set to false by default as enabling it frequently
prevents evaluation. But the plan is to eventually have it set to
true by default. Please set it to
true now in your configuration.nix
and fix all the bugs it uncovers.
The vlc package gained support for Chromecast
streaming, enabled by default. TCP port 8010 must be open for it to work,
so something like networking.firewall.allowedTCPPorts = [ 8010
]; may be required in your configuration. Also consider enabling
Accelerated Video Playback for better transcoding performance.
The following changes apply if the stateVersion is
changed to 19.09 or higher. For stateVersion = "19.03"
or lower the old behavior is preserved.
solr.package defaults to
pkgs.solr_8.
The hunspellDicts.fr-any dictionary now ships with fr_FR.{aff,dic}
which is linked to fr-toutesvariantes.{aff,dic}.
The mysql service now runs as mysql
user. Previously, systemd did execute it as root, and mysql dropped privileges
itself.
This includes ExecStartPre= and
ExecStartPost= phases.
To accomplish that, runtime and data directory setup was delegated to
RuntimeDirectory and tmpfiles.
With the upgrade to systemd version 242 the systemd-timesyncd
service is no longer using DynamicUser=yes. In order for the
upgrade to work we rely on an activation script to move the state from the old
to the new directory. The older directory (prior 19.09) was
/var/lib/private/systemd/timesync.
As long as the system.config.stateVersion is below
19.09 the state folder will migrated to its proper location
(/var/lib/systemd/timesync), if required.
The package avahi is now built to look up service
definitions from /etc/avahi/services instead of its
output directory in the nix store. Accordingly the module
now supports custom service definitions via
, which are then placed
in the aforementioned directory. See avahi.service5 for more information on custom service definitions.
Since version 0.1.19, cargo-vendor honors package
includes that are specified in the Cargo.toml
file of Rust crates. rustPlatform.buildRustPackage uses
cargo-vendor to collect and build dependent crates.
Since this change in cargo-vendor changes the set of
vendored files for most Rust packages, the hash that use used to verify
the dependencies, cargoSha256, also changes.
The cargoSha256 hashes of all in-tree derivations that
use buildRustPackage have been updated to reflect this
change. However, third-party derivations that use
buildRustPackage may have to be updated as well.
The consul package was upgraded past version 1.5,
so its deprecated legacy UI is no longer available.
The default resample-method for PulseAudio has been changed from the upstream default speex-float-1
to speex-float-5. Be aware that low-powered ARM-based and MIPS-based boards will struggle with this
so you'll need to set back to speex-float-1.
The phabricator package and associated httpd.extraSubservice, as well as the
phd service have been removed from nixpkgs due to lack of maintainer.
The mercurialhttpd.extraSubservice has been removed from nixpkgs due to lack of maintainer.
The trachttpd.extraSubservice has been removed from nixpkgs because it was unmaintained.
The foswiki package and associated httpd.extraSubservice have been removed
from nixpkgs due to lack of maintainer.
The tomcat-connectorhttpd.extraSubservice has been removed from nixpkgs.
It's now possible to change configuration in
services.nextcloud after the initial deploy
since all config parameters are persisted in an additional config file generated by the module.
Previously core configuration like database parameters were set using their imperative
installer after creating /var/lib/nextcloud.
