That similar to a problem I ran into a while back after installing
NetBSD for dual booting on a disk that already had FreeBSD installed.  I
figured out that the NetBSD disklabel command labels all slices on the
disk, even those your aren't installing NetBSD into.  Fortunately, I
saved off my FreeBSD bsdlabel output so restoring my partition layout
was easy once I figured out the situation.  And I didn't have to restore
any data either.
