Good :-)

What happened with the add_partition() and remove_partition()
methods of PedDisk?  Are they no longer needed?

Basically: I need to do this "diff" thing, anyway (with the blkpg
interface.  See the ioctl()'s in <linux/blkpg.h> in 2.4)

It looks similar... should there be generic support for this?
Is there anything that needs to be "diffed", other than the
partition numbers, partition start and partition end?
