I have a couple of small clusters (~20 nodes each) that I manage, that I'd like 
to add to my cfengine2 setup. I've hesitated because I was unsure of the 
implications of having a bunch of machines running cfengine against the same 
nfs mounted root file system.

Since all of the nodes use the same / they will all run cfengine once it's 
installed. My idea was to have only 1 or 2 of them actually do any management, 
and use classes to prevent the others from making any changes.

Something like:
no_run_node = (  )

any.!no_run_node::
   configure me!

I suspect there is a smarter way to do this based on the fact that / is mounted 
nfs. But what is it?

Thanks in advance.
