halt(1M), reboot(1M), uadmin(2), attributes(5)


Shutting down or halting the system by means of uadmin does not update

o editing of files such as /etc/system

o installing new driver binaries or kernel binaries

o updating existing driver binaries or kernel binaries.

Use reboot(1M) or halt(1M) instead.
