Are you doing a 'W'rite in the labeling tools? I'm guess that you are
not, but I wanted to be sure. You don't want to.

You say that you are doing the default partitions. If so, the 'b'
partition should be swap. It should not get 'newfs'ed. No file system
needed (or wanted) there. This tells me that something was wrong in the
partition setup if it THINKS that there is a need to newfs partition
'b'.

This is a known issue, but cosmetic in almost all cases.

I suspect that you are doing something wrong, but it's hard to figure
out just what it might be.
