  # This is a kludge. We can add the host key for the TROVE_HOST that was
  # specified, but users may access the Trove by other names, e.g. IP address
  # or domain name. Distbuild is currently not safe to run except on a private
  # network where host key checking is not important, so we disable it by
  # default to avoid errors when users don't stick to using the exact same
  # TROVE_HOST in repo URLs.
