unify_hosts.rake requires mac addresses to fully work
Description of problem:
Under some situations when dealing with the duplicate host problem, one or both of the hosts do not have a mac address. This makes the existing unify_hosts script not work properly since it is based on mac addresses for safety. We need a way to run it based purely on hostnames.
Its not clear how to get into this situation.
