upstart

reboot on init panic instead of restart

Asked by Alex Nekrasov

upstart 0.3.9

I'm trying to deal with the following situation:

- have some jobs running
- init panics. There's a core, etc. This is not a problem
- init restarts
- the jobs are still running, but initctl status does not know about it. This is a problem
- system becomes incoherent, for example Linux HA resources get cloned, etc., for they query Upstart for status. All kind of bad things happen from here on

I need to tell init to reboot the machine when it crashes or I need it to notify me right away - call or emit something, etc.

Is there a way to do that?

thanks,
Alex

No, there is no facility to do that.

Future versions will probably just let the kernel panic.

since I'm stuck with 0.3.8 on my system, if I were to do that to my version,

- where would be the right place (I think term_handler in init/main.c)?

- would you be interested in having this change delivered to you (I think not, for I'm not going to do much)
