  # This option defines the first version of NixOS you have installed on this particular machine,
  # and is used to maintain compatibility with application data (e.g. databases) created on older
  # NixOS versions. Most users should NEVER change this value after the initial install, for any
  # reason, even if you've upgraded your system to a new NixOS release. This value does NOT affect
  # the Nixpkgs version your packages and OS are pulled from, so changing it will NOT upgrade your
  # system. This value being lower than the current NixOS release does NOT mean your system is out
  # of date, out of support, or vulnerable. Do NOT change this value unless you have manually
  # inspected all the changes it would make to your configuration, and migrated your data
  # accordingly. For more information, see `man configuration.nix` or
  # https://nixos.org/manual/nixos/stable/options#opt-system.stateVersion .
