dumpVars only shows env variables which are exported 		18:51:27
@artturin:matrix.orgArtturinand substituteAll only substitutes with global vars18:51:40
@artturin:matrix.orgArtturin(because awk is used to get the vars) https://github.com/NixOS/nixpkgs/blob/a3c1a4abc78df37b537cb08414efa8eac38211b6/pkgs/stdenv/generic/setup.sh#L79018:59:32
