hello, I'm not going to comment on the patch itself, just note that dnsmasq
init script already checks for another dhcp server in the network
(dnsmasq.init:346):
udhcpc -n -q -s /bin/true -t 1 -i $ifname >&- && {
logger -t dnsmasq \
"found already running DHCP-server on interface '$ifname'" \
"refusing to start, use 'option force 1' to override"
return 0
}
perhaps this approach is enough to your use case?
