I have (access to) a NetBSD/sparc machine that's set up to dual-boot
SunOS off the same disk ("boot" gets NetBSD, "boot disk" gets SunOS).
I patched dumpfs (1.2 dumpfs, but it's rev 1.11 of dumpfs.c) with your
patch and tried it.  All three of the SunOS partitions produced

cylgrp  dynamic inodes  4.2/4.3BSD      fslevel 1

I checked them first with SunOS fsck (I love COMPAT_SUNOS :-), and they
passed cleanly.  (NetBSD fsck is mostly happy with them, but it thinks
the clean bits are wrong.  Using NetBSD newfs -O didn't work for some
reason; I had to use SunOS newfs to get filesystems SunOS fsck was
happy with.  I haven't investigated why.)

The native NetBSD filesystems on that disk showed "fslevel 3".
