I believe what is being referred to is use of the file system switch
to support MS/DOS filesystems without the use of special tools or
emulators.  SCO Xenix has a collection of commands which are
intimately familiar with the format of MS/DOS file systems.  Thus,
to edit a file on a MS/DOS partition, I must first copy the file off
of the partition and into a Xenix file.  Then I can edit it, and so
on.  Using the System V file system switch (or vnodes, or xyznodes
or whatever ...) would allow any utility to operate on any MS/DOS
file on the MS/DOS partition without the need for copying.
