Release 20.03 (“Markhor”, 2020.03/??)Highlights
In addition to numerous new and upgraded packages, this release has the
following highlights:
Support is planned until the end of October 2020, handing over to 20.09.
Postgresql for NixOS service now defaults to v11.
The graphical installer image starts the graphical session automatically.
Before you'd be greeted by a tty and asked to enter systemctl start display-manager.
It is now possible to disable the display-manager from running by selecting the Disable display-manager
quirk in the boot menu.
By default zfs pools will now be trimmed on a weekly basis.
Trimming is only done on supported devices (i.e. NVME or SSDs)
and should improve throughput and lifetime of these devices.
It is controlled by the services.zfs.trim.enable varname.
The zfs scrub service (services.zfs.autoScrub.enable)
and the zfs autosnapshot service (services.zfs.autoSnapshot.enable)
are now only enabled if zfs is set in config.boot.initrd.supportedFilesystems or
config.boot.supportedFilesystems. These lists will automatically contain
zfs as soon as any zfs mountpoint is configured in fileSystems.
nixos-option has been rewritten in C++, speeding it up, improving correctness,
and adding a option which prints all options and their values.
and options were replaced by a single option to improve support for upstream session files. If you used something like:
services.xserver.desktopManager.default = "xfce";
services.xserver.windowManager.default = "icewm";
you should change it to:
services.xserver.displayManager.defaultSession = "xfce+icewm";
New Services
The following new services were added since the last release:
The kubernetes kube-proxy now supports a new hostname configuration
services.kubernetes.proxy.hostname which has to
be set if the hostname of the node should be non default.
UPower's configuration is now managed by NixOS and can be customized
via .
Backward Incompatibilities
When upgrading from a previous release, please be aware of the following
incompatible changes:
GnuPG is now built without support for a graphical passphrase entry
by default. Please enable the gpg-agent user service
via the NixOS option programs.gnupg.agent.enable.
Note that upstream recommends using gpg-agent and
will spawn a gpg-agent on the first invocation of
GnuPG anyway.
The dynamicHosts option has been removed from the
networkd
module. Allowing (multiple) regular users to override host entries
affecting the whole system opens up a huge attack vector.
There seem to be very rare cases where this might be useful.
Consider setting system-wide host entries using
networking.hosts, provide
them via the DNS server in your network, or use
environment.etc
to add a file into /etc/NetworkManager/dnsmasq.d
reconfiguring hostsdir.
The 99-main.network file was removed. Maching all
network interfaces caused many breakages, see
#18962
and #71106.
We already don't support the global networking.useDHCP,
networking.defaultGateway and
networking.defaultGateway6 options
if networking.useNetworkd is enabled,
but direct users to configure the per-device
networking.interfaces.<name>.… options.
The stdenv now runs all bash with set -u, to catch the use of undefined variables.
Before, it itself used set -u but was careful to unset it so other packages' code ran as before.
Now, all bash code is held to the same high standard, and the rather complex stateful manipulation of the options can be discarded.
The SLIM Display Manager has been removed, as it has been unmaintained since 2013.
Consider migrating to a different display manager such as LightDM (current default in NixOS),
SDDM, GDM, or using the startx module which uses Xinitrc.
The Way Cooler wayland compositor has been removed, as the project has been officially canceled.
There are no more way-cooler attribute and programs.way-cooler options.
The BEAM package set has been deleted. You will only find there the different interpreters.
You should now use the different build tools coming with the languages with sandbox mode disabled.
There is now only one Xfce package-set and module. This means attributes, xfce4-14xfce4-12, and xfceUnstable all now point to the latest Xfce 4.14
packages. And in future NixOS releases will be the latest released version of Xfce available at the
time during the releases development (if viable).
The phpfpm module now sets
PrivateTmp=true in its systemd units for better process isolation.
If you rely on /tmp being shared with other services, explicitly override this by
setting serviceConfig.PrivateTmp to false for each phpfpm unit.
KDE’s old multimedia framework Phonon no longer supports Qt 4. For that reason, Plasma desktop also does not have option any more.
The BeeGFS module has been removed.
The osquery module has been removed.
Going forward, ~/bin in the users home directory will no longer be in PATH by default.
If you depend on this you should set the option environment.homeBinInPath to true.
The aforementioned option was added this release.
The buildRustCrate infrastructure now produces lib outputs in addition to the out output.
This has led to drastically reduced closed sizes for some rust crates since development dependencies are now in the lib output.
Pango was upgraded to 1.44, which no longer uses freetype for font loading. This means that type1
and bitmap fonts are no longer supported in applications relying on Pango for font rendering
(notably, GTK application). See
upstream issue for more information.
The packages openobex and obexftp
are no longer installed when enabling Bluetooth via
.
The dump1090 derivation has been changed to use FlightAware's dump1090
as its upstream. However, this version does not have an internal webserver anymore. The
assets in the share/dump1090 directory of the derivation can be used
in conjunction with an external webserver to replace this functionality.
The fourStore and fourStoreEndpoint modules have been removed.
Polkit no longer has the user of uid 0 (root) as an admin identity.
We now follow the upstream default of only having every member of the wheel
group admin privileged. Before it was root and members of wheel.
The positive outcome of this is pkexec GUI popups or terminal prompts
will no longer require the user to choose between two essentially equivalent
choices (whether to perform the action as themselves with wheel permissions, or as the root user).
NixOS containers no longer build NixOS manual by default. This saves evaluation time,
especially if there are many declarative containers defined. Note that this is already done
when <nixos/modules/profiles/minimal.nix> module is included
in container config.
The kresd services deprecates the interfaces option
in favor of the listenPlain option which requires full
systemd.socket compatible
declaration which always include a port.
Virtual console options have been reorganized and can be found under
a single top-level attribute: console.
The full set of changes is as follows:
i18n.consoleFont renamed to
console.font
i18n.consoleKeyMap renamed to
console.keyMap
i18n.consoleColors renamed to
console.colors
i18n.consolePackages renamed to
console.packages
i18n.consoleUseXkbConfig renamed to
console.useXkbConfig
boot.earlyVconsoleSetup renamed to
console.earlySetup
boot.extraTTYs renamed to
console.extraTTYs
The awstats module has been rewritten
to serve stats via static html pages, updated on a timer, over nginx,
instead of dynamic cgi pages over apache.
Minor changes will be required to migrate existing configurations. Details of the
required changes can seen by looking through the awstats
module.
The httpd module no longer provides options to support serving web content without defining a virtual host. As a
result of this the services.httpd.logPerVirtualHost
option now defaults to true instead of false. Please update your
configuration to make use of services.httpd.virtualHosts.
The services.httpd.virtualHosts.<name>
option has changed type from a list of submodules to an attribute set of submodules, better matching
services.nginx.virtualHosts.<name>.
This change comes with the addition of the following options which mimic the functionality of their nginx counterparts:
services.httpd.virtualHosts.<name>.addSSL,
services.httpd.virtualHosts.<name>.forceSSL,
services.httpd.virtualHosts.<name>.onlySSL,
services.httpd.virtualHosts.<name>.enableACME,
services.httpd.virtualHosts.<name>.acmeRoot, and
services.httpd.virtualHosts.<name>.useACMEHost.
For NixOS configuration options, the loaOf type has
been deprecated and will be removed in a future release. In nixpkgs,
options of this type will be changed to attrsOf
instead. If you were using one of these in your configuration, you will
see a warning suggesting what changes will be required.
For example, users.users is a
loaOf option that is commonly used as follows:
users.users =
[ { name = "me";
description = "My personal user.";
isNormalUser = true;
}
];
This should be rewritten by removing the list and using the
value of name as the name of the attribute set:
users.users.me =
{ description = "My personal user.";
isNormalUser = true;
};
For more information on this change have look at these links:
issue #1800,
PR #63103.
For NixOS modules, the types types.submodule and types.submoduleWith now support
paths as allowed values, similar to how imports supports paths.
Because of this, if you have a module that defines an option of type
either (submodule ...) path, it will break since a path
is now treated as the first type instead of the second. To fix this, change
the type to either path (submodule ...).
The Buildkite Agent
module and corresponding packages have been updated to 3.x.
While doing so, the following options have been changed:
services.buildkite-agent.meta-data has been renamed to
services.buildkite-agent.tags,
to match upstreams naming for 3.x.
Its type has also changed - it now accepts an attrset of strings.
Theservices.buildkite-agent.openssh.publicKeyPath option
has been removed, as it's not necessary to deploy public keys to clone private
repositories.
services.buildkite-agent.openssh.privateKeyPath
has been renamed to
buildkite-agent.privateSshKeyPath,
as the whole openssh now only contained that single option.
services.buildkite-agent.shell
has been introduced, allowing to specify a custom shell to be used.
Other Notable ChangesSD images are now compressed by default using bzip2.
The nginx web server previously started its master process as root
privileged, then ran worker processes as a less privileged identity user.
This was changed to start all of nginx as a less privileged user (defined by
services.nginx.user and
services.nginx.group). As a consequence, all files that
are needed for nginx to run (included configuration fragments, SSL
certificates and keys, etc.) must now be readable by this less privileged
user/group.
OpenSSH has been upgraded from 7.9 to 8.1, improving security and adding features
but with potential incompatibilities. Consult the
release announcement for more information.
PRETTY_NAME in /etc/os-release
now uses the short rather than full version string.
It is now possible to unlock LUKS-Encrypted file systems using a FIDO2 token
via .
