The latest security advisory on openssl contains the usual mantra "Restart all deamons using the library, or reboot the system." I usually just reboot but find myself wondering if there's a reliable *automatic* way of identifying which running programs use any given library (or set of libraries), and identify whether or not they're daemons controlled by service(8). I suppose root could use ps and ldd to identify affected programs, but this seems like brute force and I can't see how to tie into the service(8) structure. Anybody got ideas on this? It could be useful for updating servers you'd rather not reboot. -- Moore's Law of Mad Science: Every eighteen months, the minimum IQ necessary to destroy the world drops by one point.
