nixpkgs/etc/default.nix
Eelco Dolstra c155a3f46e * When doing chroot builds, the `build-chroot-dirs' option should
include the closure of /bin/sh.  Otherwise all builders that call
  /bin/sh will fail when using the new chroot implementation, which
  only bind-mounts the inputs of a build rather than the whole Nix
  store.
