starting - event signalling that a job is starting
starting JOB=JOB INSTANCE=INSTANCE
event is generated by the Upstart init(8)
a new instance of a job begins starting. The JOB
contains the job name, and the INSTANCE
environment variable contains
the instance name which will be empty for single-instance jobs.
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 starting.
This allows jobs to effectively insert themselves as dependencies of other jobs.
The event is typically combined with the stopped(7)
event by services.
Job configuration files may use the export
stanza to export environment
variables from their own environment into the starting
for more details.
A service that wishes to be running whenever another service would be running,
started before and stopped after it, might use:
start on starting apache
stop on stopped apache
A task that must be run before another task or service is started might use:
start on starting postgresql
