<title>Release 14.04 (“Baboon”, 2014/04/30)</title>
|
||
|
||
<para>This is the second stable release branch of NixOS. In addition
|
||
to numerous new and upgraded packages and modules, this release has
|
||
the following highlights:
|
||
|
||
<itemizedlist>
|
||
|
||
<listitem><para>Installation on UEFI systems is now supported. See
|
||
<xref linkend="sec-uefi-installation"/> for
|
||
details.</para></listitem>
|
||
|
||
<listitem><para>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.</para></listitem>
|
||
|
||
<listitem><para>NixOS is now based on Glibc 2.19 and GCC
|
||
4.8.</para></listitem>
|
||
|
||
<listitem><para>The default Linux kernel has been updated to
|
||
3.12.</para></listitem>
|
||
|
||
<listitem><para>KDE has been updated to 4.12.</para></listitem>
|
||
|
||
<listitem><para>GNOME 3.10 experimental support has been added.</para></listitem>
|
||
|
||
<listitem><para>Nix has been updated to 1.7 (<link
|
||
xlink:href="http://nixos.org/nix/manual/#ssec-relnotes-1.7">details</link>).</para></listitem>
|
||
|
||
<listitem><para>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.</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. 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.</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. 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>
|
||
|
||
</para></listitem>
|
||
|
||
</itemizedlist>
|
||
|
||
</para>
|
||
|
||
<para>When upgrading from a previous release, please be aware of the
|
||
following incompatible changes:
|
||
|
||
<itemizedlist>
|
||
|
||
<listitem><para>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’
|
||
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. 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
|
||
</programlisting>
|
||
|
||
</para></listitem>
|
||
|
||
<listitem><para>The firewall is now enabled by default. If you don’t
|
||
want this, you need to disable it explicitly:
|
||
|
||
<programlisting>
|
||
networking.firewall.enable = false;
|
||
</programlisting>
|
||
|
||
</para></listitem>
|
||
|
||
<listitem><para>The option
|
||
<option>boot.loader.grub.memtest86</option> has been renamed to
|
||
<option>boot.loader.grub.memtest86.enable</option>.</para></listitem>
|
||
|
||
<listitem><para>The <literal>mysql55</literal> service has been
|
||
merged into the <literal>mysql</literal> service, which no longer
|
||
sets a default for the option
|
||
<option>services.mysql.package</option>.</para></listitem>
|
||
|
||
<listitem><para>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.</para></listitem>
|
||
|
||
<listitem><para>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>).</para></listitem>
