  update-initramfs: Generating /boot/initrd.img-5.0.0-15-generic

  lb_chroot_hacks has a lot of code, most of which is not executed as
  far as i can tell.
  The bits that are executed are ->
  1) regenerate initrd with CASPER_UUID set => but at this point casper
  is not installed yet!
  (with UPDATE_INITRAMFS_OPTIONS set to have casper UUID thing)
  Chroot chroot "${UPDATE_INITRAMFS_OPTIONS} update-initramfs -k all -t -u"

  2) do some cleanups of files

  find chroot/boot -name 'initrd*' -print0 | xargs -r -0 chmod go+r
  # Remove cruft
  rm -f chroot/boot/initrd*bak*
  rm -f chroot/etc/apt/trusted.gpg~
  rm -f chroot/etc/group- chroot/etc/passwd-
  rm -f chroot/etc/gshadow- chroot/etc/shadow-
  rm -f chroot/var/cache/debconf/*-old
  rm -f chroot/var/lib/dpkg/*-old
  rm -f chroot/var/log/apt/term.log
  rm -f chroot/etc/adjtime

  ...

  Now after this, you can see that lb_chroot_hacks are not executed on
  any further layers!
