I have sent a patch for this upstream to Debian. Waiting for it to get accepted.

In turn, dhclient reports 'Can't bind to dhcp address: Cannot assign requested address', and fails almost immediately. It would seem that either wait-for-ll6.sh should wait for the link local address to come up AND stop being tentative, or the dhcp method for inet6 should call settle-dad.sh after wait-for-ll6? This is partly a race condition, so on slower devices the dad may complete by the time dhclient has got started, however I can regularly reproduce this on a virtual machine.
