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.</para></listitem> + + <listitem><para>NixOS now has basic container support, meaning you + can easily run a NixOS instance as a container in a NixOS host + system.

See <xref linkend="ch-containers"/> for + details.</para></listitem> + + <listitem><para>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.

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’ + has an unfree license, refusing to evaluate +</screen> + + </para></listitem> + + <listitem><para>The Adobe Flash player is no longer enabled by + default in the Firefox and Chromium wrappers.

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.</para></listitem> + + <listitem><para>The symlink <filename>/etc/ca-bundle.crt</filename> + is gone.
