<title>nixpkgs configuration</title>
<para>
The Nix package manager can be configured to allow or deny certain
package sets. At this moment, packages can either be allowed to be
installed or denied to be installed based on their license.
</para>
<itemizedlist>
<listitem>
<para>
Allow packages that do not have a free license by setting
<programlisting>
nixpkgs.config.allowUnfree = true;
</programlisting>
or deny them by setting it to <literal>false</literal>.
</para>
<para>
This can also be achieved for one call to the Nix package
manager by setting the environment variable:
<programlisting>
export NIXPKGS_ALLOW_UNFREE=1
</programlisting>
</para>
</listitem>
<listitem>
<para>
Whenever unfree packages are not allowed, single packages can
still be allowed by a predicate:
<programlisting>
nixpkgs.config.allowUnfreePredicate = (x: ...);
</programlisting>
</para>
</listitem>
<listitem>
<para>
Whenever unfree packages are not allowed, packages can still be
whitelisted by their license:
<programlisting>
nixpkgs.config.whitelistedLicenses = [ licenseA licenseB ];
</programlisting>
</para>
</listitem>
<listitem>
<para>
In addition to whitelisting licenses which are denied by the
<literal>allowUnfree</literal> setting, you can also explicitely
deny installation of packages which have a certain license:
<programlisting>
nixpkgs.config.blacklistedLicenses = [ licenseA licenseB ];
</programlisting>
</para>
</listitem>
</itemizedlist>
