But you could just as easily stick a vnd in one of the amiga partitions,
then put all the extra partitions in the vnd. That _should_ work now.

The thing which concerns me about slices is that we'll be sticking disklabels
inside of disklabels. That means a LOT of mess if it all gets rolled
into one layer of the device driver (i.e. we don't silently add vnd's
to generate the sliced-up partitions).

MRB disks must deal with this problem. I'd prefer that the other ports
not get it thrust abon them.

Take care,
