Comment 2 for bug 974284

I think the upshot here is that neither dhclient -1 nor dhclient without -1 gives us the behavior we need for reliable handling via ifupdown; so we either need to modify the behavior of -1 to be more sensible regarding dropped leases *after* the initial lease, or we need to add a new dhclient option that does the right thing. Stéphane, do you agree?
