Why are you asking on the dnsmasq list for help with this problem?

You've said the client gets no response, because the dnsmasq server is
running fsck during boot.  dnsmasq is not even running yet!  This is
the wrong place to ask for help with problems unrelated to dnsmasq.

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.
