I don't beleive we're talking about the same problem. If we move
to 16 partitions per disklabel, the obvious numbering scheme would
have minor nos. 0-15 for sd0, 16-32 for sd1, etc., but that's
incompatable with our current scheme, 0-7 for sd0, 8-15 for sd1,
etc. So if you boot up with the `wrong' kernel, you may end up
mounting partitions from sd0 instead of sd1, or mounting sd1 when
you meant to mount sd2, or whatever.
