If you kill everything then the plymouth screen will go away, NFS rootmay
fail, etc. There are other reasons it works the way it does. What is
needed is a better mechanism to notify the user of what is going on and
help them deal with it, and to also report those situations as bugs so
we can deal with them.

Title:
  Ext4 corruption associated with shutdown of Ubuntu 12.10

Status in Upstart:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete
Status in “network-manager” package in Ubuntu:
  Triaged
Status in “upstart” package in Ubuntu:
  Confirmed

Bug description:
  1. Format and label a target Ext4 partion using Ubuntu 12.04
  2. Install 64bit 12.10 OS using that target without reformatting it
  3. Shut down 
  4. Boot an alternate copy of Ubuntu
  5. Restart selecting the newly installed OS
  6. Login then shutdown
  6. Boot an alternate copy of Ubuntu
  7.Fsck the newly installed OS allowing corrections to be made

  Each time the the newly installed OS is executed and then shutdown,
  even if execution only consists of logging on, a subsequent fsck will
  FAIL.

  I used Acronis True Image Home 2013 to create an image of the newly
  installed 64-bit Ubuntu 12.10, so I can recreate the symptoms of Ext4
  filesystem corruption 100% of the time by restoring from the image,
  booting, logging on and shutting down.
