The os-term call is supposed to indicate to the platform that it should
follow it's abnormal OS termination policy. I normally set my
partitions to reboot immediately after an os-term call. I believe that
"/usr/sbin/serv_config -b" (installed with powerpc-utils-papr) is used
to set that policy from the command line.
In general, I think it's best to have the OS follow the policy stored on
the platform whenever possible. Some systems can be configured to
perform system administrator calls/pages, and there may be some other
configurable options, too; it would be a shame to have a sysadmin set up
an automatic reboot and a page, and have neither happen because he
didn't know that the default OS policy of a three-minute reboot overrode
the policy he just defined.
