[parted-devel] [PATCH] GPT & BIOS Boot partition

This patch adds support for BIOS Boot partition [1] in GPT.  It is exposed to
the user as "boot_bios" flag.

Marking partitions as bootable by BIOS allows bootloaders to know they can put
their code in them (much as they would in the 63 sector gap that DOS labels used
to provide).

GRUB 2 already embeds itself in this area whenever found (as of current CVS).

[1] Not to be confused with hybrid MBR-GPT hacks! ;-)
