  # `libxcrypt` is a dependency pretty high up in the tree. So it's hard to determine
  # from where the version comes that dovecot gets linked against (i.e. if you add `libxcrypt-legacy`
  # to `buildInputs` it's not sufficient for instance).
  # Also, patching out every possible occurrence is pretty error-prone if internal structures
  # of nixpkgs change. So instead, it's way simpler (implementation-wise, not for our Hydra)
  # to just instantiate a new nixpkgs with `libxcrypt` supporting weak hashes.
  #
  # Rather than investing more energy into a potentially nicer workaround, we should fix
  # the unterlying problem instead anyways.
