I can also confirm trusty and precise as shown above. They behave differently, in that instead of exiting failure, dhclient actually tries again and ends up getting an address. So in precise you would see: | # dhclient -6 -1 -v $dev | Internet Systems Consortium DHCP Client 4.1-ESV-R4 |

So I'm not convinced that doing this in dhclient is necessarily right. Unlike IPv4 where DHCP operates over a raw socket, in IPv6 mode, dhclient is just a regular network client and as such requires a source address to be set so it can contact the network (the link-local address in this case). As
