[Nix-dev] nix-shell and persistent environment

[Daniel Hlynskyi]

To complete previous answer.

I create a separate directory .nix-gc-roots, because nix-shell produces
many roots. Also, I haven't found yet a way to get nix root for nixpkgs
imported as external derivation, so after garbage collect I still have to
redownload some sources
