# Script to reset the firewall if, and only if, it is
# enabled as a "S" init script for this runlevel
#
# Note this script is automatically linked in to
# /etc/dhcpc/dhcpcd-<interface>.exe by the firewall script;
# if you need a custom /etc/dhcpc/dhcpcd-<interface>.exe
# app, you should be sure to call this script, too
