Some time ago, I created a simple cluster configuration kit based on CENTOS. http://gridtoys.com/pvc/pvc.html The configuration kit is based on the use of a centos kickstart DVD and a simple shell script. Now I am reading some rather fuzzy definitions for CENTOS variants and am wondering if what I am doing with the cluster configuration kit is better suited as a CENTOS variant , or if it really fits the proposed definition of a variant at all? Thanks Glen
