Make that

    $ mt -f /dev/nst0 setpart 0
    $ mt -f /dev/nst0 status 2
    $ mt -f /dev/nst0 setpart 1
    $ mt -f /dev/nst0 status 2

I wrote the setpart and mkpart commands before mt on Linux had them and
naturally they are now using different strings.  I'll have another look
into mt to make it more compatible with mt on Linux.
