    {"message":"manifest for busybox:lsfkjsdflkjsdf not found"}

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/nosuchimage:latest"
    {"message":"pull access denied for nosuchimage, repository does not exist or may require 'docker login'"}

After:

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/busybox:lsfkjsdflkjsdf"
    {"message":"manifest for busybox:lsfkjsdflkjsdf not found: manifest unknown: manifest unknown"}

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/nosuchimage:latest"
