We already have distinct bash in stdenv and user's environment.

In some sense, we have no idea whether our stdenv works on kernels older than our kernelHeaders. So the same version can be used as baseline for uname in stdenv. _______________________________________________ nix-dev mailing list nix-dev@cs.uu.nl https://mail.cs.uu.nl/mailman/listinfo/nix-dev
