Public bug reported:
When testing bug 1639930 I found that booting a system with:
ip6=dhcp
will enable ip=dhcp. ip= does not enable ip6=dhcp, so this is odd behavior.
Thus, if you had an ip6 only network, in order to do this you have to do:
ip6=dhcp ip=off
This is really just a matter of a very strange behavior, but behavior that can
be fixed by just explicitly passing ip=off.

command line
* bug 1621507: initramfs-tools configure_networking() fails to dhcp IPv6
addresses
