Hi,

  I just got off a half hour discussion with the pulp guys for the CentOS Container Pipeline registry story. 

  1. docker save x.tar produces a v1 tarball and not a v2 tarball
  2. This tarball doesnt contain metadata such as tags and so on.
  3. docker pull from docker 1.6 assumes the registry being pulled from is a v2 registry
  4. v1 registry has been depricated.
  5. Currently, the only way to get a v2 repo into pulp or any other registry is to first push it to docker registry and then sync our registry to it.
I seriously am beginning to hate docker.
