Changelog parent: 8d920803b0

New changelog entries:
  [ 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.
