Sure, there are 'other' disk partitioning tools, but the only one you really need is fdisk. And not the namby-pamby one (though the FreeDOS fdisk has potential), but the real, honest to Bob, linux fdisk. Sure, you have your Diskdrakes, your disk druids, your yasts and even your heathen Partion Magics; but when it comes down to brass tacks, is there anything so pure, powerful and simple as fdisk?
I think not. Beauty through function, my friends.
