# A configuration for Kubemark cluster. It doesn't need to be kept in
# sync with gce/config-default.sh (except the filename, because I'm reusing
# gce/util.sh script which assumes config filename), but if some things that
# are enabled by default should not run in hollow clusters, they should be disabled here.
