  # name:: a human-readable name for this distro.
  # component:: a component suitable for a packagecloud.io URL.
  # image:: a Docker image name from build_dockers without any extension.
  # equivalent:: packagecloud.io components for which we can upload the same
  # package.
  # package_type:: the extension for the package format on this OS.
  # package_tag:: the trailing component after the version number on this OS.
