Icarus,
From what I understand of riprep and sysprep is that they are supposed to be
used exclusively of each other, not in combination. Running riprep on a
system ready for uploading to RIS should take care of all of the tasks that
sysprep does with regards to removing security information from the operating
system, etc.
Qsar,
I believe that you can make as many images as you like and upload them to
RIS as long as your RIS volume has the available capacity, you just have to
use file permissions to limit which images you want certain user groups to be
able to apply.
