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";
|
||
</programlisting>

|

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.

The symlink <filename>/etc/ca-bundle.crt</filename> is gone. Programs

should instead use the environment variable

<envar>OPENSSL_X509_CERT_FILE</envar> (which points to
|
||
<filename>/etc/ssl/certs/ca-bundle.crt</filename>).
