Notwithstanding what you say above, why does the last line say "soliciting a DHCP lease"?

Also, when I try this again now, I see the following:

20160601 14:36:19.169 info daemon(dhcpcd):eth1: carrier lost
20160601 14:36:19.175 info daemon(dhcpcd):eth1: 60-netacquire: received reason=NOCARRIER, beeppid=0, ip=, sn=, gw=, dns=, options=, hn=

20160601 14:36:27.466 info daemon(dhcpcd):eth1: soliciting a DHCP lease

This doesn't have the intervening messages as the first trace regarding "rebinding" but it does end the same way: with "soliciting a DHCP lease". In both traces I never see a TIMEOUT reason code in the hook scripts (both traces are with 'lastlease' present in dhcpcd.conf).

What's going on here?

Thx,
