Yes, it should :) Now, a little history lesson: First came nova. Then, an index server was needed, and so the glance_host and glance_port options were added. Then, an enhancement: use of multiple glance hosts, and so glance_api_servers was added, with reasonable defaults drawn from glance_host and glance_port if it wasn't provided. Then, a centralized authentication service called Keystone was added, and as a benefit, it added the concept of endpoints. The reason these options have not gone away is probably a combination of supporting non-Keystone authentication and general programmer laziness… -- Kevin L.
