flat hashes can be substituted through hashed-mirrors, while recursive hashes can’t. This is especially important for Bazel since the bazel fetch dependencies can come from multiple different methods (git, http, ftp, etc.). To do this, we create tar archives from the output/external directory, which is then extracted to build. All of the Bazel hashes are all updated. Cherry-picked from 9b8ed3b

This will break packages outside of nixpkgs. I am not sure it is worth backporting? |

This is a change in interface on a stable branch. I don't think that is acceptable. |

Yes will wait on this and see if there's a way to not make it breaking. /cc @bhipple |

That's fine; I can cherry-pick it onto our 20.03 fork where it's needed and it'll drop off when we upgrade to 20.09 later this year. Since the diff is so small I don't anticipate issues. |
