Booting...
Magic numbers do not match -- improper UFS partition

You are right.  I tried netbsd-GENERICSBC in that release
and it works 
fine.  I'm going to go ahead and install the whole system
and see if I 
have the same problem with magic numbers when I reboot after
mounting 
the file system.

Ah, okay, I see it's a message of the Booter on MacOS.

Could you try to boot netbsd-GENERICSBC kernel on MacOS
partition
with a disk with the problematic UFS partition?

If it doesn't work, could you check what "disklabel
sd0"
shows on the first boot after installation?

I tried to boot netbsd-GENERIC kernel from /dev/sd0a
created
by MacOS Mkfs on my LC630 and there is no problem even
after
"mount -u -w /".
