On further examination, what the patch does is make this work:

# The mapping of nodes to roles
# installer.sh will log in to each of these nodes and then provision
# it for the specified roles.
NODES=(
  [demo.vir-test.home.arpa]=''
)

I think this triggers a default "install everything" behavior in the provision.sh script, but it would be much better (and not require the installer.sh patch) if it was written this way:

NODES=(
  [demo.vir-test.home.arpa]='database,controller,monitoring,workbench,workbench2,webshell,keepproxy,keepweb,websocket,dispatcher,keepbalance,keepstore'
)

The reason for the confusion is that local.params.example.single_host_single_hostname uses the blank version, and it wasn't tested properly.
