This isn't really a distribution-related comment but in light of Vincent's
points I think it's appropriate.  We're running diskless nodes from a single
generic root fs ramdisk which is dynamically configured at boot by a
cfengine script.  Other filesystems (ie /usr) are mounted over nfs.  
I've found
that this combination of pxelinux and cfengine is extremely powerful for
managing clusters - especially ones that tend to change frequently.
