We have a script that selects the interfaces we want perfSONAR to know 
about and generates a config file. This script queries the NAV system, 
which knows about all our boxes and interfaces.

A cron job periodically runs the script to generate a new config, and 
compares it to the config already in eXist. If it has changed, a new 
version is uploaded. We also keep a copy of the config under version 
control, so that we can keep track of how the config evolves.
