Edit this comment to match the new reality, too? I also feel like if we can use your disallowRequisites patch with this, we can skip pkgs.bash in either list, which would be best. I'd be very down to collaborate getting all the stdenv deps to use strictDeps :).

[matthewbauer]

Yeah that sounds good! It might have to go in another PR for now - I'm more worried about fixing cross compilation right now.

One thing these are all going to need though is bash in the buildInputs. I think there's quite a few of those that don't have it right now.

I think we could also do an override here that does something like:

stdenv = super.stdenv // { mkDerivation = args: super.stdenv.mkDerivation (args // { strictDeps = true; }); };

To avoid individually setting all of these.

[Ericson2314]

Well I do want to audit those packages anyways. I think I've decided this PR and the disallowRequites one are good as is, and then all the per-package cleanup can happen in a 3rd PR.
