Details:

After `update-grub` the following output is generated:

```
 menuentry 'Ubuntu, with Linux 2.6.35-22-generic (on
/dev/mapper/vvg0-root)'\'' --class gnu-linux --class gnu --class os
$menuentry_id_option
'\''osprober-gnulinux-/boot/vmlinuz-2.6.35-22-generic--0ed5e93c-99f4-48ec-8b13-1b34b52852f5
(on /dev/mapper/vvg0-root)' --class gnu-linux --class gnu --class os
$menuentry_id_option
'osprober-gnulinux-/boot/vmlinuz-2.6.35-22-generic--0ed5e93c-99f4-48ec-8b13-1b34b52852f5'
{
  insmod lvm
  insmod lvm
  insmod ext2
  set
root='lvmid/ODtXBF-9DiG-LZ2p-dI92-qJZc-9G9g-XBmgcH/grLDh5-eAcC-DEZU-gEcc-QoBR-OUlI-ik2t1l'
  if [ x$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root
--hint='lvmid/ODtXBF-9DiG-LZ2p-dI92-qJZc-9G9g-XBmgcH/grLDh5-eAcC-DEZU-gEcc-QoBR-OUlI-ik2t1l'
0ed5e93c-99f4-48ec-8b13-1b34b52852f5
  else
    search --no-floppy --fs-uuid --set=root
0ed5e93c-99f4-48ec-8b13-1b34b52852f5
  fi
  linux /boot/vmlinuz-2.6.35-22-generic
root=UUID=e673fbdf-b413-4ac9-b05c-574aa15535e4 ro vga=normal nomodeset
crashkernel=384M-2G:64M,2G-:128M nosplash
  initrd /boot/initrd.img-2.6.35-22-generic
 }
```

Note, that 'insmod lvm' is done two times. $root variable is ignored! root
option is passed like 'root=UUID=e673fbdf-b413-4ac9-b05c-574aa15535e4', all
root magic from above is ignored which leads to wrong mounted root
filesystem.

The proper menuentry should look like:

```
 menuentry 'Ubuntu, with Linux 2.6.35-22-generic (on
/dev/mapper/vvg0-root)'\'' --class gnu-linux --class gnu --class os
$menuentry_id_option
'\''osprober-gnulinux-/boot/vmlinuz-2.6.35-22-generic--0ed5e93c-99f4-48ec-8b13-1b34b52852f5
(on /dev/mapper/vvg0-root)' --class gnu-linux --class gnu --class os
$menuentry_id_option
'osprober-gnulinux-/boot/vmlinuz-2.6.35-22-generic--0ed5e93c-99f4-48ec-8b13-1b34b52852f5'
{
  insmod lvm
  insmod ext2
  set
root='lvmid/ODtXBF-9DiG-LZ2p-dI92-qJZc-9G9g-XBmgcH/grLDh5-eAcC-DEZU-gEcc-QoBR-OUlI-ik2t1l'
  if [ x$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root --hint=$root
0ed5e93c-99f4-48ec-8b13-1b34b52852f5
  else
    search --no-floppy --fs-uuid --set=root $root
  fi
  linux /boot/vmlinuz-2.6.35-22-generic root=$root ro vga=normal nomodeset
crashkernel=384M-2G:64M,2G-:128M nosplash
  initrd /boot/initrd.img-2.6.35-22-generic
 }
```

Version: 2.02~beta2-9ubuntu1
