public class Configserver
extends AbstractService

Represents a Configserver. There may be one or more Configservers in a Vespa system. NOTE: The Configserver is not started by the config system, and does not receive any config. It's included here so we know what host it runs on, and to give an error message if another service tries to reserve the ports it is using.
