Is there a way to image a stand alone system booted from a USB disk drive casting the image to the bootable USB disk drive? If so can you point me to documentation how to do it?

Currently I'm using Imaging Engine ver from Zenworks 7.? I have SLES10.2/OES2.1 servers in place but I need to image a couple of systems off the network. I am trying to get to a point I can install ZCM's latest and greatest on SLES11 with or without OES2 depending on how long it is going to take to get compatible versions of the three peices. Anyone have comments, thoughts, or recomendations?

Thanks in advance
