Many of us have servers across multiple datacenters, or have some other need for logical server grouping.

If I have a thousand servers in 25 data centers, chances are high that a lot of the parameters I want to pass to those servers are common to all of the servers in that datacenter.

For example: resolve.conf, ntp.conf, the subnet and gateway, and other assorted parameters could be the same among all of the servers in this facility.

Rather than having to define all of these parameters at the node level, we should be able to apply them once, at a "server group" level.

Currently, processing of paramaters occurs as such: global param > node param (where the node paramater overrides the global)

I'd like to see the processing be as such: global param > servergroup param > node param
