SUMMARY (2): Sun V210 and V240 resets spontaneously within jumpstart postinstall script

Although it was not my problem a very good explanation came from
"Parkes, Lloyd" <lloyd.parkes@eds.com> what can cause jumpstart
to break, by redirecting the postinstall script output to a log file.

I had this same problem. At least I think so. I haven't seen your original
message, only the subject line.

It was caused by me trying to redirect the postinstall script output to a
log file with a command like "exec > /a/var/tmp/logfile 2>&1".

The reason for this is that the postinstall script is run in a pipeline and
as soon as the script redirects its output the pipeline is broken and the
process at the end of the pipeline terminates. The Solaris installer reboots
the system as soon as the pipeline terminates, even though your script is
still running.

The answer is to stop trying to log the output from your script. It turns
out that this pipeline is only there to feed the postinstall script output
through tee(1) so that it can be logged anyway. The log file gets put under
/var/sadm on the machine being jumpstarted, but it took be a while to find
it. I can never remember the difference between /var/sadm/system/logs and   
/var/sadm/install/logs.

Cheers,
Lloyd Parkes
