Currently, we have a file directing the build for each node. However,
rebuilding just one node hardly ever makes sense, so we might as well
remove the extra files and have the user just rebuild the cluster.
With this patch, every distribution will have a basedisk scripts
configuration file (as before) and one scripts configuration file for
building the cluster (or several for building additional, different
clusters).
