[Bug 1621393] Re: xenial64 image (20160907.1.0) has a broken (empty) /etc/resolv.conf

[Launchpad Bug Tracker]

This bug was fixed in the package livecd-rootfs - 2.430

---------------
livecd-rootfs (2.430) yakkety; urgency=medium

  [ Michael Vogt ]
  * live-build/ubuntu-core/hooks/01-setup_user.chroot:
    - do not create "ubuntu" user for ubuntu-core anymore, the
      console-conf package will create this user now
  * live-build/ubuntu-core/hooks/02-add_user_to_groups.chroot
    - dropped

  [ Steve Langasek ]
  * live-build/ubuntu-cpc/hooks/042-vagrant.binary: fix unmount handling
    so that the teardown is done properly /before/ we try to make an
    image from our filesystem, since otherwise /etc/resolv.conf is broken.
    LP: #1621393.

Title:
  xenial64 image (20160907.1.0) has a broken (empty) /etc/resolv.conf

Status in cloud-images:
  New
Status in livecd-rootfs package in Ubuntu:
  Fix Released

Bug description:
  [SRU Justification]
  This is a regression introduced in the previous SRU of livecd-rootfs.

  [Test case]
  1. vagrant init ubuntu/xenial64
  2. vagrant up
  3. vagrant ssh
  4. ping google.com

  Expected result:
  - ping succeeds

  Actual result:
  - name resolution fails

  Inspecting closely reveals that this image has a 0-length
  /etc/resolv.conf.  Replacing it with a symlink to
  /run/resolvconf/resolv.conf fixes things.
