Hi Edwin,

You can map the symbolic names to the MAC addresses. On my desktop
system I have the following lines in /etc/udev/rules.d/10-network.rules

SUBSYSTEM=="net", SYSFS{address}=="xx:xx:xx:xx:xx:xx", NAME="lan0"
SUBSYSTEM=="net", SYSFS{address}=="xx:xx:xx:xx:xx:xx", NAME="wlan0"

Voyage 0.3 also uses udev, but I cannot tell which file to edit or if it
suffices to add that file.

Regards,
Paul Pichota
