Title:
  ip6=dhcp turns on ip=dhcp

Status in initramfs-tools package in Ubuntu:
  Incomplete

Bug description:
  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.
