Since Upstart does not have native state, wait-for-state is going to
need to be used for this. I have attached a modified network-interface
job and another helper job that should fix this.
# network-interface - configure network device
#
# This service causes network devices to be brought up or down as a result
# of hardware being added or removed, including that which isn't ordinarily
# removable.
