??? OK, so I give the kernel three offset/size pairs for the partitions=

my disk.

Now tell me how to address the individual partitions without minor numb=
ers
to distinguish the three. IMO there _must_ be different devices, if onl=

for security.

I, for one, definitely don't need more than that.
