I previously partitioned my disk for dual-boot, but now I don't need 
that other partition anymore. I'd like to use the now "free" space.

Is it possible to use more than one sector 0 NetBSD partition?

Or can I re-fdisk (without wiping) so that partition 0 (NetBSD) takes up 
the whole disk, and modify the disklabel to use the whole disk, then 
just create new partitions?
