On XCP, this is a file created by the host installer, containing the initial 
networking configuration. I am not sure if this applies to the Debian 
("Kronos") way?

This is a script that deals with naming (physical) network interfaces when the 
hosts starts up, and takes into account changes in the hardware (e.g. a 
replaced NIC). Again, I don't think it applies to Debian, so you can just 
remove the line.

The script is meant to completely reset the networking of your host. The main 
use case is for a pool slave that got into a bad state (for whatever reason), 
and is not able to communicate with the pool master anymore. Again, I am not 
sure if this applies to Debian, if you'd normally configure networking outside 
of xapi.

Mike, do you think xe-reset-networking is useful here at all?
