Title:
  "Previous Kernels" Entry should be there even from clean install to
  avoid breaking boot entries

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Example of problem:
  1) Do a clean install of Natty
  2) Edit grub.cfg and change DEFAULT to 3 to make Windows the default OS
  3) Update grub

  result:
  All is well until an updated kernel creates a new grub entry called "previous kernels". Now my friends machine doesn't boot because DEFAULT=3 gives a memory check (or somthing like that). So I have to manually edit grub.cfg again to make DEFAULT=4.

  Example solution:
  1)A clean install of Grub already has a "previous kernel" entry, which at this time is an empty list.
  2)Edit grub.cfg as you wish
  3)Update grub

  result:
  The DEFAULT boot entry will retain it's integrity.
