[Bug 740390] Re: libdbus-1-3 upgrade does not respawn init, resulting in unclean shutdown

[Brian Murray]

Hello Alan, or anyone else affected,

Accepted libnih into precise-proposed. The package will build now and be
available at http://launchpad.net/ubuntu/+source/libnih/1.0.3-4ubuntu9.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Changed in: libnih (Ubuntu Precise)
       Status: New => Fix Committed

** Tags added: verification-needed

Bug description:
  Binary package hint: dbus

  Steps to reproduce:
  1.  Start 20110321 daily build on Amazon EC2.
  ami-30669459 ubuntu-images-testing/ubuntu-natty-daily-amd64-server-20110321
  2.  SSH.
  3.  sudo apt-get update
  4.  To simulate an upgrade, sudo apt-get --reinstall install libdbus-1-3
  libdbus-1-3_1.4.6-1ubuntu6 is reinstalled.
  5.  sudo lsof yields (snipped)
  COMMAND   PID   USER   FD      TYPE             DEVICE SIZE/OFF       NODE NAME
  init        1   root  DEL       REG              202,1              134262 /lib/x86_64-linux-gnu/libdbus-1.so.3.5.4
  upstart-u 201   root  DEL       REG              202,1              134262 /lib/x86_64-linux-gnu/libdbus-1.so.3.5.4
  upstart-s 369   root  DEL       REG              202,1              134262 /lib/x86_64-linux-gnu/libdbus-1.so.3.5.4
  6.  sudo shutdown -h now
  Error:
  mount: / is busy

  Possible solution: touch /var/run/init.upgraded in package postinst to
  force init to respawn/close open files at shutdown. This is checked in
  /etc/rc[06].d/S60umountroot. See bug 672177 for a similar situation
  with libc6.
