Ian Wienand adb0341064 Add block-device defaults
This moves the block-device default out of the "vm" element and into a
selection of other elements.  There's "mbr" which retains the status
quo.  There's an EFI version that has the boot/grub partitions as
required.  In between there's the GPT only version, which is useful
for architectures like power without EFI, but still want possible
larger disks using GPT.
