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 overridden packages.

Specifies the Nix platform type for which NixOS should be built.

If unset, it defaults to the platform type of your host system.

Specifying this option is useful when doing distributed

multi-platform deployment, or when building virtual machines.
