>Description:

  ZIP drive on sd0, preformatted ZIP disk in drive with some stuff in its
  filesystem (FAT)

	mount_msdos -l -u ezy /dev/sd0h /zip

  Can see the fs fine.  Move around, etc.  cd into a directory with some
  files.

        touch abogusfilename.cpp
	cp abogusfilename.cpp .abogusfilenam.cpp~
	rm abogusfilename.cpp
	mv .abogusfilename.cpp~ abogusfilename.cpp

  After this, the behavior is apparently random.  Sometimes all
  the files disappear and only the touched file is present.
  Sometimes there are no files, sometimes files turn into
  directories...etc..etc.

  I have not had time to thoroughly test on other fs's (floppy), but I thought
  I'd better PR it before someone else is bit.
