If not installing in single user mode, you run the risk of not all patches
that are applicable installing properly.
Installing remotely requires console access either via a terminal server or
better yet, via the Remote System Controller (RSC) on Vx80/90 systems,
Advanced Lights Out Management (ALOM) on Vx40/20 systems.  The advantage of
RSC's and ALOM's for performing remotely is that these devices also offer
you the ability to remotely power up/down the systems.  In case of a
"lockup", at least you'd have the ability of kicking the server over and
getting the console from remote..
