Public bug reported:
Disks earlier prepared using mdadm(8) and lvm2; /boot is an md(4)
mirror, while /, /home and /var are lvm2 logical volumes. In the live
environment, I installed mdadm and lvm2 using apt-get, and started the
arrays (which also configured the volume group).
Then I started the Kubuntu installer, selected manual partitioning, and
set up the three LVs to be formatted as ext4, and md127 (/boot) to be
formatted as ext3. I chose also chose /dev/md127 as the location to
install grub.
Towards the end of the installation, an error occurred "grub-install
/dev/sda failed - this is fatal". So it looks like my choice isn't
preserved and passed through to grub-install.
In addition, manually mounting the new root & boot filesystems and
running "grub-install --boot-directory=/mnt/boot /dev/md127" also fails,
with a segfault in the underlying command "/usr/sbin/grub-setup
--directory=/mnt/boot/grub --device-map=/mnt/boot/grub/device.map
/dev/md127" :-(
