[Bug 666348] Re: Reboot notification should not require X

[Brandon Black]

[ s/exit/exist/ in near the end of the second paragraph above, typo ]

Also, as a temporary workaround, I've found that the kernel postinst
script *does* directly create /var/run/do-not-hibernate when a kernel is
upgraded, so that can be used to determine "needs reboot" as well for
now.

** Description changed:

- 
- The postinst script for Maverick (and probably other releases') kernels ultimately signal that a reboot is required by checking for and executing (if exists) "/usr/share/update-notifier/notify-reboot-required".  That script in turn generates "/var/run/reboot-required", which then other scripts (unattended-upgrade, for example) look for to indicate that a package update requires a reboot.  For that matter, /var/run/reboot-required is what any other scripts would want to look for (sysadmin's own scripts on a remote headless server? EC2?).

  The meta-problem here is that update-notifier is not normally installed
  in a headless server environment like EC2, and depends on the whole mess
  of X dependencies since it's related to graphical notifications as well.
- Thus the notify-reboot-required script does not exit, thus /var/run
+ Thus the notify-reboot-required script does not exist, thus /var/run
  /reboot-required does not get generated.
  
  The best fix would probably be to have the kernel postinst script create
  /var/run/reboot-required directly itself, in addition to executing
  update-notifier hooks if that package happens to be installed.
