+However, this will not work for <code>dwm</code>.  (Probably <code>services.xserver.windowManager.dwm</code> can only see the <code>dwm</code> in <code>pkgs</code>, not the one in <code>environment.systemPackages</code>.)  But you can use an overlay, like this:
+<syntaxhighlight lang="nix">
+nixpkgs.overlays = [
+  (self: super: {
+    dwm = super.dwm.overrideAttrs (oldAttrs: rec {
+      patches = [
+        ./path/to/my-dwm-patch.patch
+        ];
+      configFile = super.writeText "config.h" (builtins.readFile ./dwm-config.h);
+      postPatch = oldAttrs.postPatch or "" + "\necho 'Using own config file...'\n cp ${configFile} config.def.h";
+      });
+    })
+  ];
+</syntaxhighlight>
