<para>The NixOS configuration file
|
||
<filename>/etc/nixos/configuration.nix</filename> is actually a
|
||
<emphasis>Nix expression</emphasis>, which is the Nix package
|
||
manager’s purely functional language for describing how to build
|
||
packages and configurations. This means you have all the expressive
|
||
power of that language at your disposal, including the ability to
|
||
abstract over common patterns, which is very useful when managing
|
||
complex systems. The syntax and semantics of the Nix language are
|
||
fully described in the <link
|
||
xlink:href="http://nixos.org/nix/manual/#chap-writing-nix-expressions">Nix
|
||
manual</link>, but here we give a short overview of the most important
|
||
constructs useful in NixOS configuration files.</para>
