The remaining references to eth0 appear to be used only in the domU, where we control the interface names.
There is a simpler way to get the first "real" interface name which is: ls /sys/class/net | awk '$1 != "lo" { print $1; exit }' I'm not entirely convinced that this is the right thing to do; it might be as well to keep eth0 as the default. Finally the new configuration file should be documented. Ben. -- Ben Hutchings All the simple programs have been written, and all the good names taken.
