[Bug 872244] Re: grub2 recordfail logic prevents headless system from rebooting after power outage

[Richard Laager]

** Description changed:

  With the move to grub2 I recently discovered that my headless Natty
  server running as a NAS device will not reboot following a power
  failure.  I was able to track this down to the behavior of the
  'recordfail' logic in grub2.  This logic prevents grub from booting
  following an event such as a power failure.  The system boots to the
  grub2 menu and waits with no timeout (-1).
  
  While this feature may be completely appropriate for an attended desktop
  system, there should be an optional override for this behavior in the
  '/etc/default/grub' defaults file so that systems (such as headless
  ones) that need to boot following such a failure can boot without
  intervention.  I was able to work around the problem by commenting the
  following lines in /etc/grub.d/00_header
  
  #if [ ${recordfail} = 1 ]; then
-  # set timeout=-1
+  # set timeout=-1
  #else
-   set timeout=10
+   set timeout=10
  #fi
  
  An optional grub2 default parameter that emulates this logic in the
  defaults would be a nice addition so people who want the "always boot"
  behavior don't have to hack the grub scripts by hand.
