       stopping - event signalling that a job is stopping


       The stopping event is generated by the Upstart init(8) daemon when an instance of a job begins  stopping.   The
       JOB  environment  variable  contains  the job name, and the INSTANCE environment variable contains the instance
       name which will be empty for single-instance jobs.

       If the job is stopping normally, the RESULT environment variable will be ok, otherwise if the job  is  stopping
       because it has failed it will be failed.

       When  the  job has failed, the process that failed will be given in the PROCESS environment variable.  This may
       be pre-start, post-start, main, pre-stop or post-stop; it may also be the special  value  respawn  to  indicate
       that the job is stopping because it hit the respawn limit.

       Finally  in  the  case  of  a failed job, one of either EXIT_STATUS or EXIT_SIGNAL may be given to indicate the
       cause of the stop.  Either EXIT_STATUS will contain the exit status code of the process,  or  EXIT_SIGNAL  will
       contain the name of the signal that the process received.  The normal exit job configuration stanza can be used
       to prevent particular exit status values or signals resulting in a failed job, see init(5)  for  more  informa-

       If  neither EXIT_STATUS or EXIT_SIGNAL is given for a failed process, it is because the process failed to spawn
       (for example, file not found).  See the system logs for the error.

       init(8) will wait for all services started by this event to be running, all tasks started by this event to have
       finished and all jobs stopped by this event to be stopped before allowing the job to continue stopping.

       This  allows  jobs to depend on other jobs, safely stopping themselves before their dependency goes away.  This
       event is typically combined with the started(7) event by services.

       Job configuration files may use the export stanza to export environment variables from  their  own  environment
       into the stopping event.  See init(5) for more details.

       A service that wishes to depend on another service might use:

              start on started apache
              stop on stopping apache

       A task that must be run before another task or service is stopped might use:

              start on stopping postgresql RESULT=ok
