In the 1.4 days these were within epsilon of true.  They are less so
now (NetBSD now keeps a BSD label on the disk, with the Sun label kept
around just for PROM bootcode compatability, and NetBSD ffs has evolved
significantly beyond the SunOS 4.x filesystem), but I think that even
NetBSD-current can grok Sun-labeled disks and UFS filesystems.
