[Bug 251242] Re: Always kexecs on shutdown/reboot

** Description changed:

  Binary package hint: kexec-tools
  
  When I have kexec-tools installed, it seems to trigger a kexec whenever
  I shut down or reboot.  This doesn't seem like sensible default
  behavior, and my reading of the init script seems to indicate that it's
  not intentional.  It happens nonetheless, though.
  
  ===
  
  SRU Justification [Jaunty]
  
  Impact: when kexec-tools is installed reboot is optimised using kexec,
  the user no longer drops to bios nor sees their bootloader menus.  this
  should be an opt-in change as the user may install kexec to get crash
  dump functionality and is not expecting reboot to be altered.
  
  Fix Description: change the default to disable use of kexec for reboot
- by default
+ by default for new installations, for upgrades from versions before this
+ fix switch it off.
  
- Patch: http://launchpadlibrarian.net/26022183/kexec-tools-default-
- KEXEC_LOAD-false
+ Patch: http://launchpadlibrarian.net/26123164/kexec-tools-jaunty-
+ default-off-and-turn-off-KEXEC_LOAD-on-upgrade
  
  Risks: the change of default may affect previous installs
  
  TEST CASE: install kexec-tools and reboot, the bios and bootloader are
  skipped before this fix, but should not be skipped after it. Please also
  make sure to test upgrades from a system that already had kexec-tools
  installed.
