Title:
  lilo + lvm2 don't work following upgrade to breezy

Status in “lilo-installer” package in Ubuntu:
  Invalid
Status in “lilo” package in Debian:
  Invalid

Bug description:
  I cannot upgrade the kernel because of this problem when I try to run
  lilo:

  root at hal:/dev # lilo
  Warning: '/proc/partitions' does not match '/dev' directory structure.
      Name change: '/dev/dm-0' -> '/dev/dm'
  device-mapper ioctl cmd 12 failed: No such device or address
  Fatal: device-mapper: dm_task_run(DM_DEVICE_TABLE) failed

  The system was installed from a Hoary CD, with all the partitions under LVM2
  (yes, including / and /boot). It worked fine. / and /boot are ext3 partitions.
  The problem above appeared after I upgraded to breezy, therefore it is a regression.

  I am not the only one having this problem:

  I have put this bug under lilo, but it could be a number of things:
  libdevmapper, udev (it is not setting up /dev/dm-* properly, see the warning
  message above), etc, and lilo just being a victim.

  Here's the relevant lilo.conf bits:

  boot=/dev/sda
  root=/dev/mapper/vg1-root

  And the relevant extract of vgdisplay -v:
