This is my first system that uses a "MBR" type partition table
plus BSD disklabel rather than just a BSD disklabel. Most likely
I have made some MBR newbie error.
Install says:
We now have your BSD-disklabel partitions as:
This is your last chance to change them.

q: Change input units (sectors/cylinders/MB)
x: Partition sizes ok
There are (were?) two more Linux partitions between g & h in the
MBR version, but disklabel would not allow more than 16 partitions
and c & d get wasted.
It seemed happy with this. Then it said that fsck failed so
I went back to the shell and ran newfs on a, i, j, & k by
hand.
Now it is unhappy.
