Sigh.  That was not one of my better posts.  While the systems I use with
tape drives (Ultrix and Digital UNIX) do include a letter at the end of the
device name to specify density (versus the SunOS convention of using the
unit number for this purpose), they also use the "/dev/{n}rmt" prefix, and
not driver specific ones (like "/dev/wt").  Sorry for the braino.
