NetBSD/sparc has always understood native NetBSD labels.
One thing that has changed (since 1.2) is that writing disklabels is always
done by encapsulating the native NetBSD label within a SunOS-style label,
and writing that composite out to the disk. When reading back that same
composite, NetBSD will use the information in the native label, discarding
the outer SunOS layer, while SunOS will happily use _it's_ native label
format, discarding the inner NetBSD label.
Of course, to retain congruence, the SunOS restriction of starting
partitions on cylinder boundaries still applies.
