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

[Launchpad Bug Tracker]

This bug was fixed in the package dbus - 1.4.6-1ubuntu6.4

---------------
dbus (1.4.6-1ubuntu6.4) natty-security; urgency=low

  * REGRESSION FIX: some applications launched with the activation helper
    may need DBUS_STARTER_ADDRESS. (LP: #1058343)
    - debian/patches/CVE-2012-3524-regression-fix.patch: hardcode the
      starter address to the default system bus address.
  * REGRESSION FIX: unclean shutdown after dbus upgrade (LP: #740390)
    - debian/libdbus-1-3.postinst: trigger an upstart re-exec before
      shutdown or reboot so that it can safely unmount the root
      filesystem.

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.
