Currently, if you try to build a NixOS config including channel.nix, e.g.: nix-build -I nixpkgs=. -I nixos-config=nixos/modules/installer/cd-dvd/installation-cd-minimal.nix nixos -A config.system.build.isoImage twice in a row, you end up with two different build results. This is caused by the 'result' symlink of the first build affecting the channel contents of the second build. If we use filterSource with a predicate that ignores the 'result' symlinks, the problem is gone. Do the same thing for VIM/Emacs swap/backup files to avoid even more 'spurious' rebuilds. Additionally, filter out the '.git' directory at the same time, as we 'rm -rf' it from the result anyway. This avoids a considerable amount of unnecessary file I/O copying and deleting the .git directory.
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-16.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-16.09
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
