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).
