Same here, if I don't need dual-boot I always put netbsd at offset 0
on the boot disk, and it has worked fine for me so far.
Note that even if you do not run fdisk, you get a valid (though somewhat
odd) mbr partition table when you run installboot:
NetBSD disklabel disk geometry:
cylinders: 16383 heads: 16 sectors/track: 63 (1008 sectors/cylinder)
BIOS disk geometry:
cylinders: 1023 heads: 255 sectors/track: 63 (16065 sectors/cylinder)
3: sysid 169 (NetBSD)
start 0, size 16 (0 MB), flag 0x80
beg: cylinder 0, head 0, sector 1
end: cylinder 0, head 0, sector 16
On non-boot disks I have no valid mbr (at least netbsd's fdisk claims so)
and it works anyway.
