I think you both misunderstood slightly here.  I agree with what you are 
saying but you missed the point - you can't discover power parameters like 
that (AFAIK).  What I am talking about here is rack/subnet-specific things 
outside of the node's hardware.

For that sort of defaulting, I completely agree.

I'd not want to mandate a subnet for each harware type.
