I agree - heck I'm work with large Beowulves every day.

but listen to what I said. For THIS APPLICATION in a small lab,
where a researcher is looking to homebrew a system, 
I firmly believe that putting IDE drives on each node and then
installing over the network is the way ahead.

We here on the Beowulf list can argue the benefits of diskless versus
disks. 
But for someone who just wants too get something working and off the
ground, I say go the 'conventional' route.

Why take a node offline to do an update or a disk system?
