How are you planning to boot your nodes?

I have used perceus (http://www.perceus.org/) and was happy with it. 
There is also Warewulf (http://warewulf.lbl.gov or 
http://hpc.admin-magazine.com/Articles/Warewulf-Cluster-Manager-Master-and-Compute-Nodes) 
which I haven't used.

Anyone who has compared the two?
