Within reason I agree... However having things in one place defeats the high availabilty on a cluster, but we may be talking about different things here. I am looking at making Unix machines more reliable to get to 99.999% uptime. If your configuration image is on machine, than you have no backups. The cluster approach I designed has replication of configuration that covers this, so your "Cluster Monitor" node can fail-over when that machine fails (should it...).
