The option nixpkgs.hostPlatform is used but not defined.

This happens when trying to use devour like in this job:

See #23

let configForCurrentSystem = cfg: cfg.config.nixpkgs.hostPlatform.system == system;

Is this not how we check the system of a nixos configuration?

You can use nixpkgs.hostPlatform = "x86_64-linux"; in your studiopolis config to resolve this, but I'm wondering if my configForCurrentSystem should be rewritten.

I suppose I should use system:

nixpkgs has a mess of system options:

[srid]

cc @roberth - What system option should we use to answer the question "What platform this nixosconfiguration will build/run on?"

[srid]

@locallycompact Try this in the meanwhile: #26

I believe localSystem should exist for all configurations, but not entirely sure.

[roberth]

Those options aren't suitable for reading, partly because of nixpkgs.pkgs and partly because of the legacy support.

Use pkgs.stdenv.hostPlatform or pkgs.stdenv.hostPlatform.system if you need it to be a string.

[roberth]

ie the module argument

[srid]

No modules are involved, because we are dealing with the final NixOS configuration built by nixosSystem. Okay, so it should be cfg.pkgs.stdenv.hostPlatform.system. Thanks!
