In linux.dev.kernel you write:

Inserting ...
test -e /proc/sys/net/ipv4/ip_bootp_agent && \ echo 1 > /proc/sys/net/ipv4/ip_bootp_agent
... somewhere in the rc-files does the trick. It's documented in /usr/src/linux/Documentation/networking/ip-sysctl.txt

BTW: same thing for forwarding (should be first, as it changes all to forward/non-forward defaults): test -e /proc/sys/net/ipv4/ip_forwarding && \ echo 1 > /proc/sys/net/ipv4/ip_forwarding
