nixos/misc: Fix nixpkgs.config merge function #66450

infinisil · 2019-08-10T18:06:52Z

Previously nested attrsets would override each other

With this module:

{ lib, ... }: {

  nixpkgs.config = lib.mkMerge [
    { foo.bar = true; }
    { foo.baz = true; }
  ];

}

Before it would evaluate to

{ foo = { baz = true; }; }

Now it evaluates to

{ foo = { bar = true; baz = true; }; }

Fixes a problem #66448 tries to workaround

Previously nested attrsets would override each other

Can confirm that this works :)
