I see something similar on stable/11, r306639. During boot this system 
can't add its IPv6 default route. I need to add it manually 
afterwards. Note, this is on XenServer 7.0.0, so maybe the hypervisor 
play a certain role.

Also, why do the startup scripts attempt to add additional routes for 
127.0.0.1 and ::1? I see that behaviour on both head and stable/11.
