Comment 4 for bug 1148016

My understanding of this is the following:

- Neither cluster controller manages DHCP or DNS,

- initialize_node_group() is called with an enlisting node,

- find_nodegroup() cannot find a matching nodegroup for the node,

- initialize_node_group() therefore sets the node's nodegroup to the
  master nodegroup.

I'm not sure what we can do better here yet.

Andres, how much does this matter for the purposes of FPI? Can you
work around this?
