But you can rather easily have a replace_special_file program that
only specified users can run and that does nothing else.  Vi permits
shell escapes and thus like many unix programs, includes the
capabilities of all other programs so it's not something you would
want to permit a user to do as root even if you could control the
initial file loaded.
