[Beowulf] anyone using SALT on your clusters?

consider this a bit of devils advocacy and/or display of hickishness:

why the big deal about cf-engine/salt/puppet/chef/etc?
to me, a sensible cluster is nfs-root based, so there is 
hardly ever any mass-configuration to do.  when there is,
it's usually something like "pdsh -a check_something.sh".

I can easily imagine large web-based sites that might have 
lots of machines in different roles, for which these auto-devops
systems would make a lot of sense.  but even a large HPC cluster
might consist of one admin node, and identical N-1 compute nodes,
and one login node (compute node with a couple tweaks.)
an organization might well have multiple such clusters,
though that begs the question of why they are separate...
