The function [`pkgs.buildLinux`](https://github.com/NixOS/nixpkgs/blob/d77bda728d5041c1294a68fb25c79e2d161f62b9/pkgs/os-specific/linux/kernel/generic.nix) builds a kernel with [common configuration values](https://github.com/NixOS/nixpkgs/blob/d77bda728d5041c1294a68fb25c79e2d161f62b9/pkgs/os-specific/linux/kernel/common-config.nix).
This is the preferred option unless you have a very specific use case.
Most kernels packaged in Nixpkgs are built that way, and it will also generate kernels suitable for NixOS.

It has fewer additional features than `pkgs.buildLinux`, which provides common configuration values and exposes the `features` attribute, as explained below.
Both functions have an argument `kernelPatches` which should be a list of `{name, patch, extraConfig}` attribute sets, where `name` is the name of the patch (which is included in the kernel’s `meta.description` attribute), `patch` is the patch itself (possibly compressed), and `extraConfig` (optional) is a string specifying extra options to be concatenated to the kernel configuration file (`.config`).

### Additions and Improvements {#sec-nixpkgs-release-25.11-lib-additions-improvements}
-`lib.cli.toCommandLine`, `lib.cli.toCommandLineShell`, `lib.cli.toCommandLineGNU` and `lib.cli.toCommandLineShellGNU` have been added to address multiple issues in `lib.cli.toGNUCommandLine` and `lib.cli.toGNUCommandLineShell`.
-`ugrep`: Added `wrapWithFilterUtils` package flag for optionally wrapping `ugrep+` and `ug+` with filter utilities for grepping other file types.
-`ugrep`: Added `createGrepReplacementLinks` package flag for optionally creating drop-in replacement symlinks for `gnugrep`.
