The update.sh shell script now is only a call to nix-build, which does all the hard work of updating the Chromium source channels and the plugins. It results in a store path with the new sources.nix that replaces the already existing sources.nix. Along the way, this has led to a quite massive workaround, which abuses MD5 collisions to detect whether an URL is existing, because something like builtins.tryEval (builtins.fetchurl url) unfortunately doesn't work. Further explanations and implementation details are documented in the actual implementation. The drawback of this is that we don't have nice status messages anymore, but on the upside we have a more robust generation of the sources.nix file, which now also should work properly on missing upstream sources/binaries. This also makes it much easier to implement fetching non-GNU/Linux versions of Chromium and we have all values from omahaproxy available as an attribute set (see the csv2nix and channels attributes in the update attribute).

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.
