Oddly I actually boot a large cluster off a diskless image, with a local HD for file caching/work space. The boot image is relatively small (500MB). Yes this uses a little ram for the root file system on the 'diskless' node, but provides a single point of change and a reboot to update the cluster software.
xcat is used to manage the cluster and I highly recommend it. J.
