controls with the section for the other MBR-using platforms that already enable this) * Don't prompt the user to "erase the previous contents of the disk" when there's no NetBSD MBR partition; SAVEBOOTAREA is sufficient. These fixes mean that you can create a disklabel (on an i386/amd64) on a disk that doesn't have a NetBSD MBR partition without trashing the existing MBR. The previous behaviour was extremely annoying when working with media such as FAT-formatted CF cards, and didn't really protect people with such from accidentally trashing part of sector 1 of such disks, and made it extremely easy to trash sectors 0..15 of those disks instead.
