** Description changed:

+ [Impact]
+ 
+  * During upgrade to trusty, upstart would be forcefully re-executed,
+ even if it doesn't support stateful re-execution. This means all job
+ statuses is lost.
+ 
+  * Upgrade strategy for upstart is that when stateful re-execution is
+ not supported, a flag should be left to re-execute upstart on shut-down
+ only.
+ 
+  * The culprit is in libselinux1, a new dependency of upstart in trusty
+ that does not have appropriate login in its postinst.
+ 
+ [Test Case]
+ 
+  * Using precise's upstart as pid one execute:
+ $ initctl list
+ 
+  * Install libselinux1 from trusty-proposed
+  * Execute
+ $ initctl list
+ 
+  * The two lists should be largely the same, with state of jobs preserved.
+  * /var/run/init.upgraded file-flag should be present.

  Hi everyone,
  
  During troubleshooting of bug http://pad.lv/1303891 I've also discovered
  that Precise's upstart version doesn't work with Trusty's libselinux1.
  This is a major issue during a dist-upgrade from Precise to Trusty as
  upstart is severely affected by this and looses track of service PIDs
  which prevents service reloads.
  
  Can someone add a Breaks for Precise's upstart version to Trusty's
  libselinux1 debian/control file?
  
  Reproduction instructions:
  Install Ubuntu 12.04.4.
  
  $ sudo apt-get update -qq && sudo apt-get dist-upgrade -qqy
  <no output; no updates>
  
  $ initctl list
  avahi-daemon start/running, process 765
  ...
  
  $ sudo sed -i 's/precise/trusty/g' /etc/apt/sources.list
  
  $ sudo apt-get update -qq
  <no ouput; no errors>
  
  $ sudo apt-get install libselinux1 -y
  ...
  
  New dmesg lines:
  [ 256.032898] init: Re-executing /sbin/init
  
  New syslog lines:
  Apr 23 14:51:40 test upstart-socket-bridge[1090]: Disconnected from Upstart
  Apr 23 14:51:40 test upstart-udev-bridge[595]: Disconnected from Upstart
  
  $ initctl list
  avahi-daemon stop/waiting
  ...
  
  Upstart lost track of service PIDs. Commands like 'initctl reload dbus'
  will fail.
