When I push to my local repository I always see images are successfully sent but the pushing the manifest fails. An example is below:\r\n\r\n```\r\ndocker@boot2docker:~$ docker push todockerregistry.com:5000/busybox:test\r\nThe push refers to a repository [todockerregistry.com:5000/busybox] (len: 1)\r\n8c2e06607696: Image already exists \r\n6ce2e90b0bc7: Image successfully pushed \r\ncf2616975b4a: Image already exists \r\nFATA[0000] Error pushing to registry: Server error: 400 trying to push busybox:test manifest \r\n```\r\n\r\nWhen I don't map a data volume then I don't see any issues.\r\n\r\n"}}
