Title:
  Images built with "link_in_boot = yes" in /etc/kernel-img.conf end up
  with a broken /boot/initrd.img

Status in live-build package in Ubuntu:
  In Progress
Status in live-build source package in Xenial:
  Fix Committed

Bug description:
  Some architectures get "link_in_boot = yes" added to /etc/kernel-
  img.conf by lb_chroot_linux-image; it appears that cloud images built
  for these architectures (I have checked s390x and arm64) end up with
  an LZMA-compressed empty regular file at /boot/initrd.img (instead of
  the expected symlink to /boot/initrd.img-...).

  In terms of time-of-introduction, I have confirmed that an s390x image
  built against proposed on the 12th of January was good, whereas an
  s390x image built against the main archive on the 25th was not.

  (I suspect that this is actually an issue in something in the archive,
  but as I don't really know _what_, I have filed this against live-
  build for now.)

  Related bugs:
   * bug 1539157: Images built with "link_in_boot = yes" in /etc/kernel-img.conf end up with a broken /boot/initrd.img
   * bug 1536810 kernel install failed /bin/cp: cannot stat ‘/boot/initrd.img-4.3.0-7-generic’: No such file or directory

  For SRU purposes, we can confirm a fix by making sure that cloud
  images of a couple of architectures built with this fix still boot,
  and that initrd.img is a symlink rather than a (small) regular file.
