Title:
  grub-efi overwrites an existing grub*.efi file

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  On Ubuntu 12.04 (grub 1.99), grub-efi creates a
  /efi/ubuntu/grubx64.efi file, which is recognized as an entry in the
  UEFI firmware.

  When you install two Ubuntu (let's say UbuntuA, then UbuntuB) in
  dualboot, UbuntuB will overwrite the /efi/ubuntu/grubx64.efi file
  (linked to UbuntuA) by a new /efi/ubuntu/grubx64.efi file (linked to
  UbuntuB).

  THE PROBLEM IS:
  if UbuntuB's /boot/grub/grub.cfg is damaged or erased, the user can't access neither UbuntuA nor UbuntuB.

  EXPECTED BEHAVIOR:
  UbuntuA creates its own entry (eg /efi/ubuntu/grubx64_uuidA.efi ), and UbuntuB creates another entry (eg /efi/ubuntu/grubx64_uuidB.efi ), so that if UbuntuB's /boot/grub/grub.cfg is damaged, the user can still access UbuntuA via the UEFI firmware.
