# A file like this is typically copied to /usr/local/etc/rconfig/auto.sh on
# the rconfig server and the rconfig demon is run via 'rconfig -s -a'.  When
# you boot the DragonFly CD you have to bring up the network, typically
# via 'dhclient interfacename', then run 'rconfig -a' or
# 'rconfig -a ip_of_server' if the server is not on the same LAN.
