We are getting ready to upgrade our nodes to Rocks 4.1 from SuSE 9.1. However, I'm a little confused on which rolls I need to download. I downloaded the "compute" image for Opteron64. Do I also need OS Roll 1 and OS Roll 2? I noticed the "compute" image has "base", is that in place of OS Roll 1? Or is the "compute" image a combination of seperate rolls that I install after the OS?
