 The config attribute <code>boot.kernelParams</code> can be set to supply the Linux kernel with additional command line arguments at boot time.
-The following example downloads command line arguments from [https://make-linux-fast-again.com make-linux-fast-again.com] that are known to disable CPU vulnerability mitigations that have a negative performance impact on the system:
 <syntaxHighlight lang="nix">
-# file: make-linux-fast-again.nix
 { pkgs, config, ... }:
-let
+{
-  cmdline = builtins.readFile (
+   boot.kernelParams = [ /* list of command line arguments */ ];
-    builtins.fetchurl "https://make-linux-fast-again.com"
-  );
-in {
-   boot.kernelParams = pkgs.lib.splitString " " cmdline;
-}
-</syntaxHighlight>
-The easiest way to use this is to store this file in the <code>/etc/nixos</code> folder and then put it into the <code>imports</code> list in <code>/etc/nixos/configuration.nix</code> file like this:
-<syntaxHighlight lang="nix">
-{ pkgs, config, ... }:
-{
-  imports = [
-    ./make-linux-fast-again.nix
-  ];
-  # ...
 }
 </syntaxHighlight>
