[Bug 822644] [NEW] "Previous Kernels" Entry should be there even from clean install to avoid breaking boot entries

[Jarlath]

Public bug reported:

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.
