} To be blunt, given how multi-platform NetBSD is, I think we SHOULD be able

} But we need the support.

     I agree that this would be very nice.  The question is how to do
this without excessively bloating the kernel.  One way would be to
defopt it.  Another would be Charle's slices proposal.  The second
question is how do we name these partitions (and, you {general you}
thought we were having big flame wars over device naming now)?

} The place things will get harry (and which is another thread) is when we

} generated from multiple (recursed>) disklabels.

     This is precisely how MS-DOS extended partitions work.  If we
want to fully support MS-DOS partitions then we have to deal with
this.  Here's another fun one to be named.  Although, we could deal
with extended partitions as children of their root partition.
