Disable checks in a haskell package when using an overlay

Help

Overlays still such a mind blow to me, see this “Build with /nix/store/nknkgmiwm6fr2jc6xlsifi7arz7ny6la-ghc-9.2.8.” line in the build output of the concerned package.

Based on this I decided to give the following a shot based on the gist linked here:

nixpkgs.overlays = [
    (final: prev: {
      haskell = prev.haskell // {
        packages = prev.haskell.packages // {
          ghc928 = prev.haskell.packages.ghc928.override {
            overrides = hsSelf: hsSuper: {
              time-compat = prev.haskell.lib.dontCheck hsSuper.time-compat;
            };
          };
        };
      };
    })
];

Et voilà it works.
