And from the rest of this exchange, I think the word 'only' should be
added to that sentence. In other words, the XML for live setups contains
*only* what we have figured out from the live setup, completely
disregarding config files - that also leaves us room to add more live
info as we gather more. For example, the entire live XML for any
interface will now look like

        <interface name="eth0">
          <protocol family="ipv4">
            <ip address="192.168.0.52" prefix="24"/>
          </protocol>
        </interface>
        
Note that that doesn't even indicate the type of the interface (which we
may add at some point, but since we do not have that info right now, we
won't pretend we know what the interface is)
