Using the number in place of the 'f' key selects a line in the /etc/default/tar
file as the device and also gives the total blocks on the device.  Tar will
then stop before end of media and prompt for a new volume on creation.
You may also use the 'k' option to directly specify the total blocks on the
device.  I have used this to back up over multiple 60mb tapes.  (RTFM, ;-)
