Yes. 8 was always the traditional UNIX partition count. At this point, to
support more than 8 would require everyone to change their /dev/sdnX
files. Doable, but a mess.

Here's a hack of a way to fix things for now. If you feal comfortable
hacking on the disk (and have another in the computer, and have
backups), copy off the second and on sectors of the drive. They are the
partition map. Write them back out in an order with the NetBSD ones
first. MacOS doesn't care about the order, and NetBSD will find its
partitions first. Note: the order of things in the partition map
does not need to correspond to the order on disk; the partition at the back
end of the drive can be first in the table w/o problem.

Take care,
