Ok, sounds good. Is this what the object management API is intended to do, or is the main
purpose for it something else?

Actually, I really want to do the renewal from scratch, like a reboot/reinit where the client
tries to get the addresses from living leases, and if that fails it should send discover instead.
That is more like the state_init(), isn't it?

To make it work, I'll have to do it on both sides...

Why would I need to call state_init? The release for the old address is sent *after* that the client has asked for and received a new address on another subnet.
