I am considering putting WCG on a several machines that completely rebuild every morning (or on a reboot). When they rebuild, they will all get the exact same image. What would be the best way to do this so that I dont have them work on the same individual project day after day? Also is there a way to flush the cache so that I can get the most information back to the grid before it is wiped out on this rebuild?

Thanks in advance.
