[Beowulf] Request for comments: diskless cluster

[Jorge Salamero Sanz]

Hi all,

I'm going to move a 42-nodes beowulf to diskless mode (currently all local 
cloned installations).

Which system / tools do you recommend to manage the client-images ?

I was thinking on a debootstraped dir shared as NFS root. The differences 
between the nodes (/etc/hostname, /etc/fstab, /etc/exportfs ...) could be 
managed with unionfs.

Debian has a couple of tools that could help (live-helper for making custom 
images) but maybe lessdisk would be more suitable. Which one do you use ?

How do you manage this kind of cluster setup ?

Thanks !
