Hi,

fdisk -B on a disk which has no NetBSD disklabel fails because it
can't read said disklabel.

However, it seems perfectly reasonable to install a different MBR on
any disk, whether it contains or not a NetBSD system. This proves
useful if your first disk is not NetBSD-aware.

The following patch should make this possible. Anyone cares if I
commit this? The NetBSD geometry will appear as 0/0/0 if there is no
disklabel but I believe it is not used while processing the -B
option. My main concern is: how come no one stumbled on this? Am I
missing something?

regards,
 Aymeric
