Well, the way of doing /dev/hdan is too cumbersome for users/fdisk once
you also start understanding BSD slices and extended partitions...

Maybe instead of starting with /dev/hda5 we use much great minor numbers
(i.e. starting with 20 indicates extended partitions, 40 starts the
first bsd disk slice...

I'd be more than willing to see a tree like


Instead of having everything in /dev
