Bug description:
  [Impact] Installs of the original 12.04 image with 'apt-get upgrade' in their ubiquity/success_command hang.  This blocks hardware certification.
  [Test case] As below; or, more simply, put the preseed file somewhere network-accessible and boot the installer in a VM with "url=<whatever>", then run the installer with "ubiquity --automatic".  For a valid test, you need to take the original 12.04 image and upgrade just the ubiquity* binary packages before starting the installer.
  [Regression potential] It's worth testing that d-i still works when built with the updated debian-installer-utils.  Nothing outside the installer is at all likely to be affected.

  Ubuntu 12.04 release image, this contains Ubiquity 2.10.16, grub-pc
  1.99-21ubuntu3 and initramfs-tools 0.99ubuntu13. The updates install
  grub-pc 1.99-21ubuntu3.1.

  At some point between June 28th and July 3rd, the apt-get upgrade
  process on Precise installations started stalling. We've noticed it
  stops when updating the initrds for new kernels:

  Jul  4 21:17:01 ubuntu CRON[989]: (root) CMD (   cd / && run-parts --report /etc/cron.hourly)

  After the last update-initramfs line it stalls forever (notice the
  timestamp for that command and the following CRON one).

  Steps to reproduce (on any machine, this doesn't seem to be hardware-
  specific):

  - Create a nice Ubuntu 12.04 USB stick using USB disk creator (do NOT simply dd the hybrid image onto the USB stick, as you will need to write files to it later).
  - Put the attached preseed in the USB stick's preseeds directory, name it ubuntu.seed (overwriting the existing file there).
  - Edit syslinux/txt.cfg, go to the second "append" line containing kernel parameters for the "install ubuntu" menu option (line 9 in the file), and right after "only-ubiquity", add a space and "automatic-ubiquity".
  - Boot a test system with this USB stick
  - Select the "install ubuntu" option

  Expected result:
  - System installs ubuntu completely, prompts to reboot and boots into a complete installation

  Actual result:
  - System will stall forever
  - Log shows as seen above.

  The main addition to the preseed is the late_command:

  ubiquity ubiquity/success_command string \
  for i in /dev /dev/pts /dev/shm /sys /sys/kernel/security /proc /cdrom; do mount --bind $i /      target/$i; done; \
    sed -i -e "/^GRUB_CMDLINE_LINUX_DEFAULT/s/\"$/ initcall_debug\"/" /target/etc/default/grub;     chroot /target update-grub; \
    echo "echo 0 > /sys/module/kernel/parameters/initcall_debug" > /target/etc/initramfs-tools/conf.d/initcall; chroot /target update-initramfs -u; \
    for i in /dev/pts /dev/shm /dev /sys/kernel/security /sys /proc /cdrom; do umount $i; done; \
    in-target apt-get update; \
    in-target apt-get upgrade -y --force-yes; \
    true

  Note this late_command basically just apt-get updates and upgrades.
  The first few lines are apparently needed if some of the later updates
  include a kernel update; without the mounts, the implicit update-grub
  in /target will fail.
