reboot(1m) does not cause a system hang
In
previous releases, a reboot(1m) issued typically by Software Distributor
utilities (swinstall/swremove) terminated the iswd daemon thereby causing the system hang due to the inability
of processes executing during reboot to access iSCSI devices. This
problem has been resolved.
The following message will be displayed during execution of
shutdown(1m) or reboot(1m).
reboot: CAUTION: some process(es)
wouldn’t die
This message is the result of the iswd daemon being kept alive
to complete various tasks during reboot. When iSCSI is configured
in a system, this message may be ignored.
