AFAIK everything landed for this already in zesty (and thus in artful as
well). Not sure why it is still "In Progress".

I'm setting this to Fix Released; if there are any other issues anyway,
they should get their own bug so we can better track any possible SRUs.

Bug description:
  [Impact]
   * initramfs-tools SRUs introduced regressions in ip= syntax, which cause unexpected behavior

  [Test Case]
   * Create a machine that boots using an nfsroot.
   * Use ip=:::::eth0:dhcp on the kernel command line.  To set up
     networking.
   * Discover that the device never comes up because, networking is not configured correctly.

  [Regression Potential]
  Should be back to original behavior before ipv6 support was introduced in the past 2 or 3 SRUs.

  [Other Info]

   * There are a number of other issues in this code base that are not solved by this fix.
     - The ?*:?*:?*:?*: use case falls through to the default case, and likely breaks there.  As such static assignment via ip= appears broken
     -
   * The networking configuration does not strictly follow the kernel documentation as described https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt . This should be fixed.

  This bug is a regression of changes made under bug 1628306.

  ====================Original Bug Description Follows==================

  initramfs-tools 0.122ubuntu8.3 introduced a serious regression where
  networking is not initialized when the boot option "ip=dhcp" is
  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.
