Grab a snapshot of Marcel's gpt tool. This is still a work-in-progress but is useful to have handy. EFI GPT partitions are used instead of the fdisk+disklabel combination. They are pure 64 bit LBA, are fully extensible, support up to 16383 partitons per disk, etc.

o Newer EFI implementations require that a GPT is preceeded by a PMBR. Make sure the create command creates a PMBR as well (if not already present). o When parsing the MBR, explicitly check for a PMBR and create a PMBR map node if one is found. o When parsing the MBR, recurse to handle extended partitions. This allows us to flatten nested MBRs when migrating to a GPT. o Have the migrate command bail out if it encounters a partition it doesn't know how to migrate. This avoids data loss. o Change the output of the show command so that the UUIDs of the GPT partitions fit on the same line. o Show when partitions are extended partitions and add the PMBR type.

Implement a remove command. The remove command iterates the GPT partitions and removes any that matches the pre-conditions. The options are the same for the add command and are used to select the partitions to remove. Currently the remove command without any options deletes all GPT partitions. This is rather harmful and will need anti-footshooting measures.

o Add functionality to add a GPT partition, o Use DCE compliant UUID functions and provide local implementations if they don't exist, o Move dumping of the map to show.c and print the partition type, o Some cleanups and rearrangements. The default GPT partition type is UFS. When no starting block or size are specified, the tool will create a partition in the first free space it find (or that fits, depending on the size).
