Once the job has failed and is respawned, the status becomes `docker respawn/post-start` after subsequent failures (as opposed to `docker stop/post-start`), so the post-start script needs to take this into account. I could not find specific documentation on the job transitioning to the `respawn/post-start` state, but this was observed on Ubuntu 14.04.2. Signed-off-by: Lewis Marshall <lewis@lmars.net>
