       See `pkgs/os-specific/linux/kernel/generic.nix` for details on how these arguments

     

       105

       affect the generated configuration. You can also build a custom version of Linux by calling

     

       106
       +
       `pkgs.buildLinux` directly, which requires the `src` and `version` arguments to be specified.

       114

       Note that this method will use the common configuration defined in `pkgs/os-specific/linux/kernel/common-config.nix`,

     

       115
       +
       which is suitable for a NixOS system.
