# parabola changes and rationale:
# - Added i686 and armv7h
# - Added prepare() to change the default docker registry from
#   docker.io (because it contains nonfree software and no policies
#   against that). to localhost:5000. See the postinstall message for
#   more details.
# - Added postinstall message to warn about the default repository change.

  # - We currently need to use registry-1.docker.io instead of
  #   docker.io. For instance:
  #   sudo docker run -it --rm \
  #        registry-1.docker.io/pureos/byzantium bash -c "echo hello world"
  #   This needs to be fixed for keeping the compatibility with docker
  #
  # - Check if all docker work fine. For instance do DockerFiles still
  #   refer to the registry-1.docker.io repository? What about other
  #   parts of Docker?
  #
  # - Find an FSDG compliant repository and Use another example:
  #   - moby/vendor/github.com/docker/distribution/registry/api/v2/descriptors.go
  #   - moby/vendor/github.com/docker/distribution/registry/client/auth/session.go
  #
  # - Fix Documentation:
  #   - cli/docs/reference/commandline/tag.md
  #   - cli/man/src/image/pull.md
  #   - cli/man/src/image/tag.md
