Interactive 2.2 has both the collection-of-tools (actually bundled
into one, "dossette", which you can run either interactively or not),
AND the ability to mount a DOS partition or floppy (it seems that
for some reasone you can only mount a DOS partition on a hard disk if
that disk ALSO has a Unix partition - don't know if it's a bug or a
feature) with the mount -f DOS switch (or mount's auto-fs-sensing
feature). It seems a reasonable approach; the special purpose tool
is faster for typical usage (grab a few files of a floppy), mounting
allows full-range operation. There IS a bug in mounting a DOS12
partition - if you have more than 64 files in a directory, there
will be malfunctions (severe ones!); it's also indispensable to
up the NDOSINODES undocumented variable (as I believe Conor showed
a few months ago) from its default, currently 400.
