blagg page thingy became private 🤔

I just updated to the latest nixpkgs and I am suddenly having some issues with digga's mkTest, the nodes in the test no longer have system defined, here is an example from a repl:

nix-repl> Flake.checks.x86_64-linux.customTestFor-vmIso-simple-trilium.system
"x86_64-linux"

nix-repl> Flake.checks.x86_64-linux.customTestFor-vmIso-simple-trilium.passthru.nodes.machine.pkgs.system
error: attribute 'system' missing

       at «string»:1:1:

            1| Flake.checks.x86_64-linux.customTestFor-vmIso-simple-trilium.passthru.nodes.machine.pkgs.system
             | ^
            2|

I'm having a look to see why this is, but any advice / thoughts are welcome

This was insanely difficult to track down (5-6hrs lost on this) as the stack track was not useful at all. The only thing that caused the error was this one LoC, and I don't really understand how it could cause the config to no longer have the system attribute as no where in the stack trace referenced anything related to this.

  nixpkgs.config.allowUnfree = false;

Is your config public? Or I can try to reproduce it later with my setup.

Hey. I'm wondering, is it possible to run deploy from x86_64-darwin host? Or I should stop trying and run it on a VM? The error I encounter is this:

error: a 'x86_64-linux' with features {} is required to build '/nix/store/1z6p4anlsbbyv4gkcck6jdzdj0qi1jzj-builder.pl.drv', but I am a 'x86_64-darwin' with features {benchmark, big-parallel, nixos-test, recursive-nix}
🚀 ❌ [deploy] [ERROR] Failed to check deployment: Nix checking command resulted in a bad exit code: Some(1)

my config is not public, but it is trivial to reproduce, simply use unstable as your nixos input and add nixpkgs.config.allowUnfree = false; to a host config with a custom test (which can be an empty custom test)

In reply to @pachumicchu:myrdd.info
boot.binfmt.emulatedSystems = [ "x86_64-linux" ];
But I don't know if there is something like that for darwin.

I suppose, I should be using extraConfig, but will it work? As I undestand, lib.mapAttrs returns a list? In other languages, recursiveUpdate would operate on maps instead of lists, right?
