A solution to this issue is to abandon generic interface names and assign descriptive ones. To do this, udev provides a way of renaming network devices depending on their unique MAC hardware address:

KERNEL="eth*", SYSFS{address}="00:02:3f:46:de:ad:be:ef", NAME="fw"

Adding this line to a file in /etc/udev/rules.d/ instructs udev to rename the netork interface with the entered MAC address to "fw", indicating the firewire interface. You can do the same with your WLAN and LAN interfaces, so that you end up with descriptive names for all of your network devices.

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
#
# This file has been modified to use user mode linux
# processes on this machine - the installed software
# makes some assumptions on the naming of the tap devices
# (to be more precise the numbering). So if you like to
# use further uml processes with networking, use tap devices
# starting from tap4.
