-/* struct's hacked from Linux source: fs/partitions/mac.h
- * I believe it was originally written by Paul Mackerras (from comments in
- * Quik source)
- *
- * See also:
- * http://developer.apple.com/documentation/mac/Devices/Devices-126.html
- * http://developer.apple.com/documentation/mac/Devices/Devices-121.html
- * http://devworld.apple.com/technotes/tn/tn1189.html
- *
- * Partition types:
- * Apple_Bootstrap new-world (HFS) boot partition
- * Apple_partition_map partition map (table)
- * Apple_Driver device driver
- * Apple_Driver43 SCSI Manager 4.3 device driver
- * Apple_MFS original Macintosh File System
- * Apple_HFS Hierarchical File System (and +)
- * Apple_HFSX HFS+ with case sensitivity and more
- * Apple_UNIX_SVR2 UNIX file system (UFS?)
- * Apple_PRODOS ProDOS file system
- * Apple_Free unused space
- * Apple_Scratch empty
- * Apple_Void padding for iso9660
- * Apple_Extra an unused partition map entry
- *
- * Quick explanation:
- * ------------------
- * Terminology:
- *
- * Parted Apple
- * ------ -----
- * device disk/device
- * disk no equivalent.
- * partition volume or partition
- * sector block
- *
- * * All space must be accounted for, except block 0 (driver block) and
- * block 1-X (the partition map: i.e. lots of MacRawPartitions)
- *
- * * It's really hard to grow/shrink the number of MacRawPartition
- * entries in the partition map, because the first partition starts
- * immediately after the partition map. When we can move the start of
- * HFS and ext2 partitions, this problem will disappear ;-)
