This patch change the behaviour or overridePackages: - Before, overridePackages was based on top of the set of packages overriden by `~/.nixpkgs/config.nix` file. - After, overridePackages should when given a function f, behave almost¹ the same as-if the packageOverrides attribute of `~/.nixpkgs/config.nix` file attribute was set to f, assuming that we ignore the extra `self` argument. ¹ It is not yet exactly the same because we have many paths which are re-entering nixpkgs while taking the default attributes, such as the bootstrap phase of stdenv. Thus if the nixpkgs configuration overrides any of the dependencies need for the bootstrap, then we might get different sha.
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-15.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-15.09
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
