This is a major closure size reduction on Darwin, and probably a less significant one on Linux. On darwin, retaining the compiler means adding clang and its dependency llvm to the perl closure, which gives us ~400MB of extra stuff. Considering that Nix itself depends on this version of perl, that makes cutting a new Nix release rather unpleasaont Darwin. After this patch, I was able to get the `nixUnstable` closure down to 21MB after feeding it into a .tar.xz (123MB before compression). There's still room for improvement but this should carry us over until we split outputs.
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.
