/*
|
|
Invoke NixOS. Unlike traditional NixOS, this does not include all modules.
|
|
Any such modules have to be explicitly added via the `modules` parameter,
|
|
or imported using `imports` in a module.
|
|
|
|
A minimal module list improves NixOS evaluation performance and allows
|
|
modules to be independently usable, supporting new use cases.
|
|
|
|
Parameters:
|
|
|
|
modules: A list of modules that constitute the configuration.
|
|
|
|
specialArgs: An attribute set of module arguments. Unlike
|
|
`config._module.args`, these are available for use in
|
|
`imports`.
|
|
`config._module.args` should be preferred when possible.
|
|
|
|
Return:
|
|
|
|
An attribute set containing `config.system.build.toplevel` among other
|
|
attributes. See `lib.evalModules` in the Nixpkgs library.
