Systemd has been updated to version 212, which has <link xlink:href="http://cgit.freedesktop.org/systemd/systemd/plain/NEWS?id=v212">numerous improvements</link>. NixOS now automatically starts systemd user instances when you log in. You can define global user units through the <option>systemd.unit.*</option> options.

NixOS now supports fully declarative management of users and groups. If you set <option>users.mutableUsers</option> to <literal>false</literal>, then the contents of <filename>/etc/passwd</filename> and <filename>/etc/group</filename> will be <link
|
||
xlink:href="https://www.usenix.org/legacy/event/lisa02/tech/full_papers/traugott/traugott_html/">congruent</link> to your NixOS configuration. For instance, if you remove a user from <option>users.extraUsers</option> and run <command>nixos-rebuild</command>, the user account will cease to exist. Also, imperative commands for managing users and groups, such as <command>useradd</command>, are no longer available. If <option>users.mutableUsers</option> is <literal>true</literal> (the default), then behaviour is unchanged from NixOS 13.10.

NixOS now has basic container support, meaning you can easily run a NixOS instance as a container in a NixOS host system. These containers are suitable for testing and experimentation but not production use, since they’re not fully isolated from the host. See <xref linkend="ch-containers"/> for details.

Systemd units provided by packages can now be overridden from the NixOS configuration. For instance, if a package <literal>foo</literal> provides systemd units, you can say:
|
||
<programlisting>
|
||
systemd.packages = [ pkgs.foo ];
|
||
</programlisting>
|
||
to enable those units. You can then set or override unit options in the usual way, e.g.
|
||
<programlisting>
|
||
systemd.services.foo.wantedBy = [ "multi-user.target" ];
|
||
systemd.services.foo.serviceConfig.MemoryLimit = "512M";

Nixpkgs no longer exposes unfree packages by default. If your NixOS configuration requires unfree packages from Nixpkgs, you need to enable support for them explicitly by setting:
|
||
<programlisting>
|
||
nixpkgs.config.allowUnfree = true;
|
||
</programlisting>
|
||
Otherwise, you get an error message such as:
|
||
<screen>
|
||
error: package ‘nvidia-x11-331.49-3.12.17’ in ‘…/nvidia-x11/default.nix:56’

The Adobe Flash player is no longer enabled by default in the Firefox and Chromium wrappers. To enable it, you must set:
|
||
<programlisting>
|
||
nixpkgs.config.allowUnfree = true;
|
||
nixpkgs.config.firefox.enableAdobeFlash = true; # for Firefox
|

nixpkgs.config.chromium.enableAdobeFlash = true; # for Chromium

The firewall is now enabled by default. If you don’t want this, you need to disable it explicitly:

networking.firewall.enable = false;

Package variants are now differentiated by suffixing the name, rather than the version. For instance, <filename>sqlite-3.8.4.3-interactive</filename> is now called <filename>sqlite-interactive-3.8.4.3</filename>. This ensures that <literal>nix-env -i sqlite</literal> is unambiguous, and that <literal>nix-env -u</literal> won’t “upgrade” <literal>sqlite</literal> to <literal>sqlite-interactive</literal> or vice versa. Notably, this change affects the Firefox wrapper (which provides plugins), as it is now called <literal>firefox-wrapper</literal>. So when using <command>nix-env</command>, you should do <literal>nix-env -e firefox; nix-env -i firefox-wrapper</literal> if you want to keep using the wrapper. This change does not affect declarative package management, since attribute names like <literal>pkgs.firefoxWrapper</literal> were already unambiguous.
