Bug Description
During installation of Trusty on a RAID6/LVM system, the installation fails during the "configure" phase of grub-efi-amd64. The installer message says "GRUB installation failed
The 'grub-efi-
The installer log message screen says (among other things):
grub-install: error: cannot open `/boot/
After issuing:
chroot /target
grub-install -v
... the installation of grub also ends with:
grub-install: info: copying `/boot/
grub-install: error: cannot open `/boot/
Installation is on a raid6 (software-raid) device with lvm, /dev/mapper/

Further research shows:
- a simple install with sda1 = fat32 EFI, sda2 = 100Gb ext4 does work
- an install with /dev/md0 formatted as ext4 root-fs fails
- an install with /dev/sda2 as LVM pv, with root as a volume within, fails too.
Both md and lvm installs initially seem to complain that "grub-install dummy" failed. Trying to run grub-install from the command line will then show the error about the missing "load.cfg".
Rather weird is the fact that Bug #1236625 seems to describe the exact same issue - but was fixed in grub2 - 2.00-19ubuntu2. Is this a regression?
