User-space programs should not be using headers extracted from random kernels, but should in fact use the headers that were used to build libc; see e.g., this LKML posting by Linus Torvalds on the subject of Linux API headers at [1]. What is more, the Linux API headers are supposed to be backwards compatible[2], so there's really no good reason to have more than one such package, namely the latest one required by a package in our tree. That is, `kernelHeaders` is not only incorrect but serves no real purpose: out-of-tree modules use the sources provided by `kernel.dev`; user space should use `stdenv.cc.libc.linuxHeaders` or the top-level `linuxHeaders` attribute. Apart from klibc, nothing in nixpkgs used `linuxPackages.kernelHeaders`, so the impact of this change is minimal.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-16.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-16.03
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
