Public bug reported:
After upgrading to quantal, grub-install says:
Path `/boot/grub' is not readable by GRUB on boot. Installation is
impossible. Aborting.
My setup is 2x1TB raid1 disks. LVM on raid. /boot in LVM. This
configuration was working before quantal. Currently I'm rebuilding my
raid 'cos it was mdraid10 on GPT, and I tought GPT was making grub-
install fail, but now it is mdraid1 on MBR and the problem persists.
Maybe it is md or lvm problem (from the message "missing modules from
core image").
