Here is a better diff of the change I made to /etc/grub.d/00_header to
work around the problem

Title:
  grub2 recordfail logic prevents headless system from rebooting after
  power outage

Status in “grub2” package in Ubuntu:
  New

Bug description:
  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
  #else
    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.
