[Bug 616287] Re: umountfs doesn't cleanly unmount / on reboot

[Clint Byrum]

piwacet, I think we need to fix it in Natty and all other supported
release, yes. However, other things have taken priority over this
particular fix. If somebody wants to backport the change from oneiric to
11.04 I'd be quite happy to sponsor that upload. Please see
https://wiki.ubuntu.com/StableReleaseUpdates for help on how to get it
ready for upload.

Bug description:
  Binary package hint: initscripts

  Sometimes (ca. 50% of cases) when rebooting or turning off the
  computer, the console shows shortly before shutting down (analogous;
  plymouth disabled):

  [...]
  unmounting weak filesystems ...
  mount: / is busy
  [...]

  At next reboot, my root filesystem is recognised as needing recovery, e.g.:
  [    2.720951] EXT4-fs (sda5): INFO: recovery required on readonly filesystem
  [    2.721033] EXT4-fs (sda5): write access will be enabled during recovery
  [    4.925307] EXT4-fs (sda5): orphan cleanup on readonly fs
  [    4.939550] EXT4-fs (sda5): ext4_orphan_cleanup: deleting unreferenced inode 16472
  [    4.952641] EXT4-fs (sda5): 1 orphan inode deleted
  [    4.952696] EXT4-fs (sda5): recovery complete
  [    5.717403] EXT4-fs (sda5): mounted filesystem with ordered data mode. Opts: (null)
