  linux-boot-prober yields wrong uuid for kernel root parameter

Status in os-prober package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: os-prober

  My Partitions:
  sda5 swap

  linux-boot-prober doesn't take the root partition as kernel root
  paraameter for my karmic installation.

  I suspect that when I try to boot my karmic, it boots the karmic
  kernel with lucid userland -> nothing works.
