Well how much of an issue that is depends on how many scripts there
are that use fdisk. My impression was that fdisk is mostly a manual
tool, but that's only an impression. Anyway, the old versions could be
kept but set to do a warn() if used, and then in a few versions time
they could be removed all together.
