Solved "ntfs-3g <part> <mountpoint>" mounts NTFS under v10

I couldn't get mount -t ntfs-3g /dev/ada1s1 /I to work under 10.3. It complained "operation not supported by device" .

But the man page ntfs-3g(8) says that ntfs-3g <part> <mountpoint> will work and in fact ntfs-3g /dev/ada1s1 /I mounted fine for me. (Why some people need to gratuitously mess with standard syntax and meanings puzzles me, but it seems to be an annoyingly common problem)

So if you're having a problem mounting an NTFS slice under v10, try leaving off the mount -t part of the command.
