The `PYTHONNOUSERSITE` was exported to prevent impurities during runtime. The downside of exporting environment variables is that they always propagate all the way down the process tree, unless they are explicitly unset at some point. Using the `-s` argument applies it only to the process executed in the wrapper. That way, subprocesses are free to do impure things.
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-17.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-17.09
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
