[Dnsmasq-discuss] increasing boot timeout

Indeed, if a client get a reply from the server, it will boot. There is no problem with that. The problem is sometimes (in case of power on/off), the clients pass the POST and want to get an IP from server, but the server is doing fsck and has not started the network yet. As a result, the client will give up.

At the time you want to change the behavior of the client, has it
received any message from dnsmasq yet?
