Description of problem:
~ $ sudo service docker-registry start
[sudo] password for misc:
Redirecting to /bin/systemctl start docker-registry.service
Failed to start docker-registry.service: Unit redis.service failed to load: No such file or directory.
There is no hard requirement for redis.service to be on the same system, and I am not even sure redis is required for anything. SO this requirement should be relaxed.
Yup, redis was only a caching requirement. 0.7.3 will get rid of it.
This has been in fixed in 0.7.3-1
