[Dnsmasq-discuss] old event to dhcp-script on lease expiry

So, if I understand correctly, there is no way to maintain the leases
file database *and* have my own script catch all events? Why does
dnsmasq put such restrictions? It would be cool to have both
concurrently.

Another question, not very much related to dnsmasq, is that when a
machine receives a lease for a particular period, when should it query
the DHCP again for a new lease? Is it bound to do so, by some RFC? Or
is a matter of choice by the developer?
