[BAD, don't do this] wrapBinary for wrapping chromium with additional flags (not sure if i like this yet)

.nixpkgs.config.nix

with import <nixpkgs> {};

let 

  # wrapBinary builds a new derivation that wraps the given package and binary file with makeWrapper,
  # using the given params. Supports wrapping a binary without forcing a recompilation.
  #  * name    - Package name
  #  * package - The package we are wrapping 
  #  * binary  - Binary the binary name within $package/bin/$binary
  #  * params  - The parameters passed to makeWrapper
  wrapBinary = { name, package, binary, params }: stdenv.mkDerivation {
    inherit name;
    src = pkgs.writeText "src" ''
    
    '';
    phases = [ "installPhase" ];
    buildInputs = [ package pkgs.makeWrapper ];
    installPhase = '' makeWrapper ${package}/bin/${binary} $out/bin/${binary} ${params} '';
  };

in
{
  packageOverrides = pkgs: {
    chromium_dpi = wrapBinary {
      name = "chromium-dpi";
      package = pkgs.chromium;
      binary = "chromium";
      params = ''--add-flags "--force-device-scale-factor=1"'';
    };
  };
}
