/etc/arff reads RT-11 (acutally FILES-11) file systems.  Ultrix 2.x
(maybe 1.x as well) has what looks like a complete rewrite of arff, so
with any luck it should work on any FILES-11 structure.  I know from
experimental evidence that 4.3BSD arff works on 8200 RX50s (although if
you try to `create' a file system, it will leave too few free blocks;
so I `create' new floppies by copying existing DEC floppies with dd).
