If you try to volcopy using a no rewind device, volcopy will skip
over the file created by labelit(1M) and create a second file on the
tape with the proper information.  It does this w/o any error message,
since it obviously opens the tape to read in the label, then closes
and reopens to write the data.  With a rewind device, the tape would
supposedly reposition itself to the begining of the tape and overwrite
the label.  I see no apparent fix, since the System V tape driver does
not have ioctl calls to skip around the tape with.
