# udhcpc hook script for rayhunter WiFi client mode.
# Saves DHCP lease info (gateway, DNS) so the daemon can read the real
# gateway even when subnets collide. Routing is handled by the daemon.
#
# Deployed to /data/rayhunter/udhcpc-hook.sh by the installer.
# Any installer that adds wifi-client support must also deploy this script.
