The "stopped" event has special arguments when Upstart stops a job due
to failed respawn, as described in stopped(7):
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 was stopped
because it hit the respawn limit.
This means that you could just do (as a file in /etc/init):
start on stopped $JOB RESULT=failed PROCESS=respawn
You can make that more generic if you like, a job that should cause a
reboot when respawn fails could have (in its config file):
Then your reboot job could match it with:
start on stopped REBOOT_ON_RESPAWN_FAIL=1 \
I'm not totally convinced that reboot-on-respawn-fail is a sufficiently
common use case to have a built in especially for it, especially since
you can get the behaviour you want already :-)
Have you ever, ever felt like this?
Had strange things happen? Are you going round the twist?
