If I'm not mistaken, the ctx broker is my "base-cluster.xml", so I'd like to put
there the params before running the cluster, like this
<role name="CreateUser" user group shell uid gid />
I don't know if it's possible, all the VMs will receive the same parameters.

I checked the nfs server and client and torque master and slave under 1 and 4
and them all read this:
"called with IP, short hostname and hostname (args $1, $2, and $3 respectively)"

Torque seemed to receive parameters:
hostname="true" pubkey="true"
but I haven't found where are they used in the scripts.
