Title:
  Default values for WAIT_STATE are wrong in the upstart wait-for-state
  job

Status in upstart package in Ubuntu:
  Confirmed

Bug description:
  In Ubuntu 14.04, the wait-for-state job uses the env vars
  WAIT_STATE="started" or WAIT_STATE="stopped". if the GOAL env var is
  set to 'start' or 'stop'.

  However, according to the upstart cookbook, the desired states for a
  already started/stopped job are 'start/running' and 'stop/waiting'.
  Maybe a misunderstood has occurred was the meaning of signals was job
  states (for example, after a job reaches the start/running state, it
  emits the started signal).

  The strange thing is that the waiting/running wait states were
  proposed at the first implementations of this job, and not the
  stopped/started states: https://lists.ubuntu.com/archives/upstart-
  devel/2011-February/001405.html.

  This  bug can make some developers to write upstart jobs that return
  errors (like the GlusterFS developers, that forgot the
  WAIT_STATE="running" condition).
