In reading John Siracusa's review of Leopard (
http://arstechnica.com/reviews/os/mac-os-x-10-5.ars/ ), I encountered
a reference to the sandbox definitions in /usr/share/sandbox .
Interestingly, to this lisp weenie, they're encoded in lisp-like
syntax. For example, here's /usr/share/sandbox/bsd.sb :

;;
;; common rules for various BSD daemons
;; Copyright (c) 2007 Apple Inc.  All Rights reserved.
;;
;; WARNING: The sandbox rules in this file currently constitute
;; Apple System Private Interface and are subject to change at any time and
;; without notice. The contents of this file are also auto-generated and not
;; user editable; it may be overwritten at any time.
