Comment 8 for bug 1487041

Sadly odhcp6c also failed to acquire an address in my deployments, so I made another switch to dhclient from the ISC DHCP package now and that is working fine for me.

I also added an init script that will run rdisc in order to find out whether dhcpv6 should be used. The patch can be found at lp:~j-rosenboom-j/cirros/dev and it would be great if someone else could test this, too.
