# would be cool if services that provide an interface could use
# the same name as each other. e.g. for anything implementing
# addressProvider you might expect (output svc "address") or
# (output svc "family") to work. Otherwise switching a network link
# from static to dhcp might require reviewing all the downstreams
# that refer to it.
# Also, services should declare the outputs they provide
