Comment 9 for bug 1487041

I tried to acquire an IPv6 with the latest image version of cirros and it doesn't work. odhcp6c seems to fail for me (and also I don't think there is any mechanism AFAIK to use this binary at boot time to get IPv6).

Then I tried to use the cirros image with the @j-harbott patch, and it worked with a small modification (the init script for the IPv6 was failing at boot time, but if you execute it login into the machine, it worked). I needed to add a `sleep(5)` in the init script before executing the `dhclient -6` to make it not fail. Probably I could be hitting this bug: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1447715
