init 6
hello,
i am running a process on a solaris10 machine. this process is supposed to print some messages just before the machine is restarted.
in the manual of init i see that my process should receive a SIGTERM signal and only after 5 seconds a SIGKILL should be sent.
when performing init 6, my process does not receive the SIGTERM signal.
i put a K01myprocess in /etc/rc3.d in order to send the SIGTERM to the process myself however when K01myprocess is ran, the process is already dead.
also, my process sometimes receives a SIGHUP signal before the reboot, but not always.
can someone please clarify what actions are done when performing init 6 and what should i do to insure my process receives the SIGTERM.
these are my machine's details:
SunOS 5.10 Generic sun4u sparc SUNW,Netra-240
thanks,
Amit

Scripts in rc3 are run when you go to rc3, not when you leave rc3.
If you want to run a script when the machine shuts down, you should put it in /etc/rc0.d.

I would never rely on getting a signal at shutdown. I would either use an rc script in rc0.d, or I would construct it as a valid Solaris 10 Service, and have SMF call the stop method at the correct point in time.
