Got it; the other distro doesn't put the PReP partition on the RAID/md
device itself -- it uses the (non-RAID) partition on /one/ of the
underlying block devices.

# lsblk

  I am trying to install Ubuntu14.04 on the firestone machine on a RAID1 array, configured with software raid.
  Installation goes on smoothly till its reaches grub loader and fails. Below I have pasted the error.

  grub-installer pieces from syslog

  Aug 19 11:07:43 grub-installer: info: Installing grub on '/dev/md0p1'
  Aug 19 11:07:43 grub-installer: info: grub-install does not support --no-floppy
  Aug 19 11:07:43 grub-installer: info: Running chroot /target grub-install  --force "/dev/md0p1"
  Aug 19 11:07:43 grub-installer: Installing for powerpc-ieee1275 platform.
  Aug 19 11:08:01 grub-installer: grub-install: error: failed to copy Grub to the PReP partition.
  Aug 19 11:08:01 grub-installer: error: Running 'grub-install  --force "/dev/md0p1"' failed.

  and the "error:" message 'failed to copy Grub to the PReP partition.'
  is not generated by the grub-installer script itself [1], so probably
  coming down from grub2.

  I'd suggest to either involve our grub2 guy (not sure if available),
  or mirroring to Canonical.
