** Description changed:

  SRU Justification:
  
  Impact: When /boot and / are in an LVM VG and a snapshot is made of an
  LVM LV in that VG the system will not boot and grub can not be modified
- (updated, reinstalled.)
+ (updated, reinstalled) until all snapshots are removed.
  
  Testcase:
  
  Binary package hint: grub2
  
  Steps to reproduce:
  
  - (Lucid beta2 installed from CD)
  - Take a snapshot of any volume
  - on reboot:
    error: fd0 read error.
    error: no such disk.
    grub rescue>
  - Use the rescue cd to get a root shell
  - Remove the snapshot and reboot
  Now, the system boots. Create a new snapshot to repeat.
  
  The system has 2 SATA disks in mdadm RAID1 configuration with 1 lvm
  volume on top and no 'normal' partitions.
