# Our redundant-interface script will do that for us
# We can't use /etc/hostname.<int> and /etc/hosts entries, as the boot
# sequence will automatically ifconfig up all interfaces configured that way
#
# If things are lovey dovey, we have an exit code of 0. 
# If there's no config file, that's bad, so we print an error message and bomb
# with an exit code of 2
