I'm trying to migrate from the dedicated Lix module to the nixpkgs built-in Lix. IIUC, the manual recommends this:

  nixpkgs.overlays = [
    (final: prev: {
      inherit (prev.lixPackageSets.stable)
        nixpkgs-review
        nix-eval-jobs
        nix-fast-build
        colmena
        ;
    })
  ];

  nix.package = pkgs.lixPackageSets.stable.lix;

However, that throws an infinite recursion for nixpkgs-review. I do have a couple more overlays, but they are not interacting with nixpkgs-review in any obvious way.

What could be the culprit, how to debug?

So, a bit more tinkering revealed that most but not all of the overrides cause the issue:

• nixpkgs-review: causes infinite recursion
• nix-eval-jobs: No problem
• nix-fast-build: causes infinite recursion
• colmena: causes infinite recursion

Here is a minimal repro for playing:

{ pkgs, ... }:

{
  nixpkgs.hostPlatform = "x86_64-linux";

  # TODO debug why this yields infinite recursion
  nixpkgs.overlays = [
    (final: prev: {
      inherit (prev.lixPackageSets.stable)
        nixpkgs-review
        nix-eval-jobs
        nix-fast-build
        colmena
        ;
    })
  ];

  nix.package = pkgs.lixPackageSets.stable.lix;
  environment.systemPackages = with pkgs; [
    nixpkgs-review
    nix-eval-jobs
    nix-fast-build
    colmena
  ];

  boot.isContainer = true;
  fileSystems."/".fsType = "tmpfs";
}

In reply to @wucke13:matrix.org
just1602 That works without doubt, of course. But I would expect the mechanism advertised on https://lix.systems/add-to-config/ to work, too. And of course having the overlay is a bit more convenient.

random consideration, would it make sense to add some parameters to nix log (and related) so it is easier to wrangle it to a file, specify explicitely if it should use a pager and such niceties

or is this too much polishing a 💩, while the ways of handling this with normal unix tricks makes sense to most

Does Lix support the lfs input attribute? I'm trying to follow https://github.com/Gigahawk/sarugetchu_mm_patcher/blob/master/README.md#usage but Lix doesn't seem to support them.

$  nix build -L --refresh 'git+https://github.com/Gigahawk/sarugetchu_mm_patcher.git?lfs=1#iso-patched'
error: unsupported input attribute 'lfs' for the 'git' scheme
