"Can't be hacked." If the program cannot ever open a file for writing,
then holes in the wrapper script or the program itself cannot result
in files on the server being altered. He's not worried about me, he's
worried about people hacking the tools I install. You can tell him
"there's a mode that chooses not to write", and his answer will be
"there's a hack which can change the mode". You can't prove him
wrong, but you can make a tool which cannot be hacked by simply
removing all the "open" calls which write files.
