     4: Subject: Provide HASKELL_PACKAGES override for all nix-eval runners
     5: Message-Id: <9c18593ec86cb062-0-artemis@nixos>
     6: resolution: fixed
     7: 
     8: We run QuickSpec using nix-eval, which provides NIX_EVAL_HASKELL_PKGS as
     9: an override if we want to alter the source of Haskell packages. Since
    10: our QuickSpec runners hard-code NIX_EVAL_HASKELL_PKGS for our own
    11: purposes, this prevents users specifying their own override.
    12: 
    13: In the case of nix-support/quickspecEnv.nix, we provide our own override
    14: HASKELL_PACKAGES. This is good, and should be made available by our
    15: other hard-coded values of NIX_EVAL_HASKELL_PKGS too.
