nixpkgs/pkgs/build-support/usernixos/bashrc.nix
Lluís Batlle i Rossell 68b5044cc0 Adding 'usernixos', where I start a modular kind-of-nixos that can go into
"nix-env -i" profiles, as a container for flexible configuration at the style
of nixos, to be defined in .nixpkgs/config.nix, with the main target of
generating an activation script.
