[Bug 1065801] Re: New grub boot menu fails to show device designations

[Erick Brunzell]

And just handing boot off to an older grub2 OS results in ridiculously
long and sometimes totally incorrect menu items like:

menuentry "Ubuntu quantal (development branch), kernel 3.5.0-15-generic (on /dev/sda15)' --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-/boot/vmlinuz-3.5.0-15-generic--562a6d98-7630-445d-b3eb-186990955537 (on /dev/sda16)" --class gnu-linux --class gnu --class os {
	insmod part_msdos
	insmod ext2
	set root='(hd0,msdos16)'
	search --no-floppy --fs-uuid --set=root f3221ba1-36a8-42d5-9205-8d873e8ecb4f
	linux /boot/vmlinuz-3.5.0-15-generic root=UUID=562a6d98-7630-445d-b3eb-186990955537 ro quiet splash
	initrd /boot/initrd.img-3.5.0-15-generic
}
menuentry "Ubuntu quantal (development branch), kernel 3.5.0-15-generic (recovery mode) (on /dev/sda15)' --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-/boot/vmlinuz-3.5.0-15-generic-root=UUID=562a6d98-7630-445d-b3eb-186990955537 ro single-562a6d98-7630-445d-b3eb-186990955537 (on /dev/sda16)" --class gnu-linux --class gnu --class os {
	insmod part_msdos
	insmod ext2
	set root='(hd0,msdos16)'
	search --no-floppy --fs-uuid --set=root f3221ba1-36a8-42d5-9205-8d873e8ecb4f
	linux /boot/vmlinuz-3.5.0-15-generic root=UUID=562a6d98-7630-445d-b3eb-186990955537 ro single
	initrd /boot/initrd.img-3.5.0-15-generic

You'll notice in one place it mentions sda15 but in another it mentions
sda16.

So booting the correct OS is now like rolling the dice.

Title:
  New grub boot menu fails to show device designations

Status in “grub2” package in Ubuntu:
  New

Bug description:
  I realize that this is somewhat intentional with the upgrade to grub
  2.* but the new grub really is virtually worthless with a complex
  multi-boot because it fails to show device designations such as (sda2)
  etc.

  I'll review this tomorrow and add more info after looking through the
  logs.
