[Ganglia-general] overriding the location variable

[Doug Nordwall]

I'm attempting to use the rack view in the new ganglia, and I do not 
want to be forced to custom write out a gmond.conf for every node in 
the cluster.  Currently, the location variable is gathered from there, 
and I don't appear to be able to override it with gmetric. I have a 
script that will get the rank/rack/plane in the right format...so how 
might I get it in there?
