[Launchpad Bug Tracker]

This bug was fixed in the package libsepol - 2.2-1ubuntu0.1

---------------
libsepol (2.2-1ubuntu0.1) trusty; urgency=medium

  [ Laurent Bigonville ]
  * Drop debian/libsepol1.postinst: Which had unguarded `telinit u' call,
    which is not strictly needed and otherwise causes unwatned side
    effects to the init process. (Closes: #753727) (LP: #1331555)

  Trusty's libsepol1 causes issues with Precise's Upstart during dist-
  upgrade

Status in libsepol source package in Trusty:

Status in libsepol source package in Utopic:

Status in libsepol package in Debian:

Bug description:
  Trusty's libsepol1 (2.2-1) has no Upstart version check for the
  'telinit u' call. During the dist-upgrade from Precise to Trusty this
  causes Upstart to loose its state. Because of this Upstart no longer
  knows which PIDs running services have and thus all service reloads
  fail.

  This bug is similarly to bug http://pad.lv/1313712 and the same fix
  applies.

  Faulty code:
  if [ "$1" = "configure" ]; then
   # Restart init. If it fails, there is nothing we can do, so
   # just ignore the error (NOTE: Borrowed from libc6.postinst)
   telinit u 2>/dev/null || true ; sleep 1
  fi

  Correct code:
  if [ "$1" = "configure" ]; then
   # Restart init. If it fails, there is nothing we can do, so
   # just ignore the error (NOTE: Borrowed from libc6.postinst)
   if dpkg --compare-versions "$UPSTART_VERSION_RUNNING" ge 1.6.1; then
    telinit u 2>/dev/null || true ; sleep 1
   fi
  fi

  
  accepted fix in debian packaging is to drop the postinst all together, since none of the libsepol symbols are used by neither upstart or systemd.
