Comment 83 for bug 1065281

I ran some experiments today and this so far seems to be the 'sweet spot' with regard to the EFI system partition:

1) Before installing, I created a 133MB partition on my gpt disk using parted, type FAT32 and bootable.
2) I formatted the partition using "mkfs.vfat -s1 /dev/sda1"
3) Booted to the 13.10 server installer.
4) At partitioning time, I chose 'manual', and did not touch the EFI system partition (things looked to be recognized properly by the installer, anyway, in that regard). I created a root and swap partition on the disk with the remaining space.
5) Proceeded with the installation.
6) Upon reboot, EFI (for the first time ever) was able to attempt booting automatically from the system partition on this type of hard drive. I was dropped to a grub prompt, but, this is a huge improvement over where we were earlier.

I also repeated the above using what we're currently setting the EFI partition to (which is around 100MB) and the *only* way I could get the system to try and boot was to manually drill down to the grubx64.efi / shimx64.efi via the 'Boot from file' option in the EFI menu.
