The configuration of the Nix Packages collection. (For

|
details, see the Nixpkgs documentation.) It allows you to set
|
|
package configuration options, and to override packages
|
|
globally through the <varname>packageOverrides</varname>
|
|
option. The latter is a function that takes as an argument
|
|
the <emphasis>original</emphasis> Nixpkgs, and must evaluate
|
|
to a set of new or overriden packages.

Specifies the Nix platform type for which NixOS should be built.
|
|
If unset, it defaults to the platform type of your host system
|
|
(<literal>${builtins.currentSystem}</literal>).
|
|
Specifying this option is useful when doing distributed
|
|
multi-platform deployment, or when building virtual machines.
