following incompatible changes:</para>

<itemizedlist>
|

|

<listitem>
|

<para>We no longer produce graphical ISO images and VirtualBox
|

images for <literal>i686-linux</literal>. A minimal ISO image is
|
||
still provided.</para>
|
||
</listitem>
|
||
|

<listitem>
|
||
<para>Firefox and similar browsers are now <emphasis>wrapped by default</emphasis>.
|
||
The package and attribute names are plain <literal>firefox</literal>
|
||
or <literal>midori</literal>, etc. Backward-compatibility attributes were set up,
|
||
but note that <command>nix-env -u</command> will <emphasis>not</emphasis> update
|
||
your current <literal>firefox-with-plugins</literal>;
|
||
you have to uninstall it and install <literal>firefox</literal> instead.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><command>wmiiSnap</command> has been replaced with
|
||
<command>wmii_hg</command>, but
|
||
<command>services.xserver.windowManager.wmii.enable</command> has
|
||
been updated respectively so this only affects you if you have
|
||
explicitly installed <command>wmiiSnap</command>.
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><literal>jobs</literal> NixOS option has been removed. It served as
|
||
compatibility layer between Upstart jobs and SystemD services. All services
|
||
have been rewritten to use <literal>systemd.services</literal></para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><command>wmiimenu</command> is removed, as it has been
|

removed by the developers upstream. Use <command>wimenu</command>
|
||
from the <command>wmii-hg</command> package.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para>Gitit is no longer automatically added to the module list in
|
||
NixOS and as such there will not be any manual entries for it. You
|
||
will need to add an import statement to your NixOS configuration
|
||
in order to use it, e.g.
|
||
|
||
<programlisting><![CDATA[
|
||
{
|
||
imports = [ <nixpkgs/nixos/modules/services/misc/gitit.nix> ];
|
||
}
|

]]></programlisting>
|
||
|
||
will include the Gitit service configuration options.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><command>nginx</command> does not accept flags for enabling and
|
||
disabling modules anymore. Instead it accepts <literal>modules</literal>
|
||
argument, which is a list of modules to be built in. All modules now
|
||
reside in <literal>nginxModules</literal> set. Example configuration:
|
||
|
||
<programlisting><![CDATA[
|
||
nginx.override {
|
||
modules = [ nginxModules.rtmp nginxModules.dav nginxModules.moreheaders ];
|
||
}
|

]]></programlisting>
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><command>s3sync</command> is removed, as it hasn't been
|
||
developed by upstream for 4 years and only runs with ruby 1.8.
|
||
For an actively-developer alternative look at
|
||
<command>tarsnap</command> and others.
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><command>ruby_1_8</command> has been removed as it's not
|
||
supported from upstream anymore and probably contains security
|
||
issues.
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><literal>tidy-html5</literal> package is removed.
|
||
Upstream only provided <literal>(lib)tidy5</literal> during development,
|
||
and now they went back to <literal>(lib)tidy</literal> to work as a drop-in
|
||
replacement of the original package that has been unmaintained for years.
|
||
You can (still) use the <literal>html-tidy</literal> package, which got updated
|
||
to a stable release from this new upstream.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><literal>extraDeviceOptions</literal> argument is removed
|
||
from <literal>bumblebee</literal> package. Instead there are
|
||
now two separate arguments: <literal>extraNvidiaDeviceOptions</literal>
|
||
and <literal>extraNouveauDeviceOptions</literal> for setting
|
||
extra X11 options for nvidia and nouveau drivers, respectively.
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para>The <literal>Ctrl+Alt+Backspace</literal> key combination
|
||
no longer kills the X server by default.
|
||
There's a new option <option>services.xserver.enableCtrlAltBackspace</option>
|
||
allowing to enable the combination again.
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><literal>emacsPackagesNg</literal> now contains all packages
|
||
from the ELPA, MELPA, and MELPA Stable repositories.
|
||
</para>
|

</listitem>
|
||
|
||
<listitem>
|
||
<para>Data directory for Postfix MTA server is moved from
|
||
<filename>/var/postfix</filename> to <filename>/var/lib/postfix</filename>.
|
||
Old configurations are migrated automatically. <literal>service.postfix</literal>
|
||
module has also received many improvements, such as correct directories' access
|
||
rights, new <literal>aliasFiles</literal> and <literal>mapFiles</literal>
|
||
options and more.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para>Filesystem options should now be configured as a list of strings, not
|
||
a comma-separated string. The old style will continue to work, but print a
|
||
warning, until the 16.09 release. An example of the new style:
|
||
|
||
<programlisting>
|
||
fileSystems."/example" = {
|
||
device = "/dev/sdc";
|
||
fsType = "btrfs";
|
||
options = [ "noatime" "compress=lzo" "space_cache" "autodefrag" ];
|
||
};
|
||
</programlisting>
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para>CUPS, installed by <literal>services.printing</literal> module, now
|
||
has its data directory in <filename>/var/lib/cups</filename>. Old
|
||
configurations from <filename>/etc/cups</filename> are moved there
|
||
automatically, but there might be problems. Also configuration options
|
||
<literal>services.printing.cupsdConf</literal> and
|
||
<literal>services.printing.cupsdFilesConf</literal> were removed
|
||
because they had been allowing one to override configuration variables
|
||
required for CUPS to work at all on NixOS. For most use cases,
|
||
<literal>services.printing.extraConf</literal> and new option
|
||
<literal>services.printing.extraFilesConf</literal> should be enough;
|
||
if you encounter a situation when they are not, please file a bug.</para>
|
||
|
||
<para>There are also Gutenprint improvements; in particular, a new option
|
||
<literal>services.printing.gutenprint</literal> is added to enable automatic
|
||
updating of Gutenprint PPMs; it's greatly recommended to enable it instead
|
||
of adding <literal>gutenprint</literal> to the <literal>drivers</literal> list.
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><literal>services.xserver.vaapiDrivers</literal> has been removed. Use
|
||
<literal>services.hardware.opengl.extraPackages{,32}</literal> instead. You can
|
||
also specify VDPAU drivers there.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para>
|
||
<literal>programs.ibus</literal> moved to <literal>i18n.inputMethod.ibus</literal>.
|
||
The option <literal>programs.ibus.plugins</literal> changed to <literal>i18n.inputMethod.ibus.engines</literal>
|
||
and the option to enable ibus changed from <literal>programs.ibus.enable</literal> to
|
||
<literal>i18n.inputMethod.enabled</literal>.
|
||
<literal>i18n.inputMethod.enabled</literal> should be set to the used input method name,
|
||
<literal>"ibus"</literal> for ibus.
|
||
An example of the new style:
|
||
|
||
<programlisting>
|
||
i18n.inputMethod.enabled = "ibus";
|
||
i18n.inputMethod.ibus.engines = with pkgs.ibus-engines; [ anthy mozc ];
|
||
</programlisting>
|
||
|
||
That is equivalent to the old version:
|
||
|
||
<programlisting>
|
||
programs.ibus.enable = true;
|
||
programs.ibus.plugins = with pkgs; [ ibus-anthy mozc ];
|
||
</programlisting>
|
||
|
||
</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para><literal>services.udev.extraRules</literal> option now writes rules
|
||
to <filename>99-local.rules</filename> instead of <filename>10-local.rules</filename>.
|
||
This makes all the user rules apply after others, so their results wouldn't be
|
||
overriden by anything else.</para>
|
||
</listitem>
|
||
|
||
<listitem>
|
||
<para>Large parts of the <literal>services.gitlab</literal> module has been
|
||
been rewritten. There are new configuration options available. The
|
||
<literal>stateDir</literal> option was renamned to
|
||
<literal>statePath</literal> and the <literal>satellitesDir</literal> option
|
||
was removed. Please review the currently available options.</para>
|
||
</listitem>
|
||
|

<listitem>

<para>
|
||
The option <option>services.nsd.zones.<name>.data</option> no

longer interpret the dollar sign ($) as a shell variable, as such it

||
should not be escaped anymore. Thus the following zone data:
|

</para>
|

\$ORIGIN example.com.
|

\$TTL 1800
|
