Global _PedDiskOps::partition_new )(const PedDisk *disk, PedPartitionType part_type, const PedFileSystemType *fs_type, PedSector start, PedSector end)

add label guessing op here

Global _PedDiskType::name

not very intuitive name

Global ped_geometry_check (PedGeometry *geom, void *buffer, PedSector buffer_size, PedSector offset, PedSector granularity, PedSector count, PedTimer *timer)

use ped_device_check()

Global ped_partition_get_flag (const PedPartition *part, PedPartitionFlag flag)

Where's the check for flag availability?
