Bug Description

Since Grub2, Grub is also able to boot from a GPT disk even on legacy BIOS systems. GPT is more flexible in the naming or amount of partitions and more robust.

The only 'disadvantage' I could come up with would be if someone decides to install a secondary OS on a legacy BIOS system that does not handle GPT disks after Ubuntu was installed first with a GPT disk. This is somewhat a rare case. Even for Window-Dualboot setups, Windwos is usually installed first because it nukes the boot code anyways. If Ubuntu is installed as a second OS, it will not re-write the partition table anyways.

Thus I suggest defaulting to GPT for new partition tables (with protective MBR, as partman/parted should automatically do) even for smaller disk. :)
