Title:
  grub2 doesn't recognize installations with encrypted /

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub-common

  After installing Ubuntu 10.04 (Lucid Lynx) Alpha 3, my previous Ubuntu
  installation is not listed in grub boot menu when its root partition
  (/) is encrypted (dm-crypt). "sudo grub-mkconfig" does not find my
  previous installation either. One has to edit grub config files
  manually to boot the previous installation.

  To reproduce this bug:
  Install any version of Ubuntu to a "dm-crypt"-encrypted root partition (/) using a un-encrypted /boot-Partition.
  Install Lucid Lynx Alpha 3 to a different "dm-crypt"-encrypted root-partition (/) using a different un-encrypted /boot-Partition.
  (You have to use the alternate CD to install Ubuntu to a "dm-crypt"-encrypted root partition (/).)
  Try to find the Ubuntu you installed first in your grub boot menu.
  Try to find the primarily installed Ubuntu by executing "sudo grub-mkconfig".
