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

[piwacet]

I had a go at this.

I'm not a technical person, and can not vouch for the technical accuracy
of this.  Thanks for looking at this, and if I've done this incorrectly,
I apologize for wasting people's time.

In a freshly installed  virtualbox ubuntu natty, I verified that the
procedure in comment #71 does in fact cause this problem, and that
making changes to /etc/init.d/sendsigs from this patch:

http://launchpadlibrarian.net/73183009/sysvinit_2.87dsf-4ubuntu24_2
.87dsf-4ubuntu25.diff.gz

does fix the problem.  (This patch is based on codewarrior's patch from
comment #65.)

I made a debdiff based on the natty package "sysvinit - 2.87dsf-
4ubuntu23" with the change to /etc/init.d/sendsigs incorporated,
following this procedure ("Tutorial 1: Providing a Debdiff"):

https://wiki.ubuntu.com/PackagingGuide/HandsOn

I'll attach the debdiff.

Again, if I've done this incorrectly, sorry for wasting people's time.
I could likely make another attempt at this if there is a better way.
Thanks!

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)
