If set, the pkgs argument to all NixOS modules is the value of
|
2022-08-15 05:16:25 +00:00
|
|
|
this option, extended with `nixpkgs.overlays`, if
|
|
|
|
that is also set. Either `nixpkgs.crossSystem` or
|
|
|
|
`nixpkgs.localSystem` will be used in an assertion
|
2018-11-10 22:21:21 +00:00
|
|
|
to check that the NixOS and Nixpkgs architectures match. Any
|
2022-08-15 05:16:25 +00:00
|
|
|
other options in `nixpkgs.*`, notably `config`,
|
2018-11-10 22:21:21 +00:00
|
|
|
will be ignored.
|
|
|
|
|
|
|
|
If unset, the pkgs argument to all NixOS modules is determined
|
|
|
|
as shown in the default value for this option.
|
|
|
|
|
|
|
|
The default value imports the Nixpkgs source files
|
2018-01-10 14:19:37 +00:00
|
|
|
relative to the location of this NixOS module, because
|
|
|
|
NixOS and Nixpkgs are distributed together for consistency,
|
2022-08-15 05:16:25 +00:00
|
|
|
so the `nixos` in the default value is in fact a
|
|
|
|
relative path. The `config`, `overlays`,
|
|
|
|
`localSystem`, and `crossSystem` come
|
2018-04-05 19:22:45 +00:00
|
|
|
from this option's siblings.
|
2018-01-10 14:19:37 +00:00
|
|
|
|
|
|
|
This option can be used by applications like NixOps to increase
|
|
|
|
the performance of evaluation, or to create packages that depend
|
|
|
|
on a container that should be built with the exact same evaluation
|
|
|
|
of Nixpkgs, for example. Applications like this should set
|
2022-08-15 05:16:25 +00:00
|
|
|
their default value using `lib.mkDefault`, so
|
2018-01-10 14:19:37 +00:00
|
|
|
user-provided configuration can override it without using
|
2022-08-15 05:16:25 +00:00
|
|
|
`lib`.
|
2018-01-10 14:19:37 +00:00
|
|
|
|
|
|
|
Note that using a distinct version of Nixpkgs with NixOS may
|
|
|
|
be an unexpected source of problems. Use this option with care.

do not need to specify this option, unless cross-compiling, in which case

2022-08-05 17:39:00 +00:00

you should set *only* {option}`nixpkgs.buildPlatform`.

the platform *for* which NixOS should be
