"df" does not work the way you expect for all versions of UNIX.  In
particular, most older AT&T derived UNIX systems do not give the filesystem
for a given file.

Short of writing C code, I don't know of any mechanism for doing what
you want.  [ You could fondle the mount table and see what mount point
has the appropriate path prefix, but that is not guaranteed to work ]
