Hi Eelco,

This does'nt work with
nix-env -aq '*'
to list all packages (the mypackage and all from pkgs)

I'm looking for something like 
==
with (import /pr/nix/nixsvn/trace/nixpkgs/trunk/pkgs/top-level/all-packages.nix {});
rec {
  mypackage = stdenv.mkDerivation {
    name = "mypackage";
  };
  inherit transfig, ...;
  # I'd like to do a inherit *;
}

... are all remeaning packages not listed yet but defined in
all-packages.nix

Then I don't need to specify the nix file and can install all at once.

Is this possible somehow ?
