Who says running as UID == 0 gives you all capabilities? Why have a distinguished root user at all? OTOH, it does make sense to have a program that can modify files belonging to DNS, and which is allowed to bind to a low port, but nothing else. The UID/GID (and ACL) stuff and capabilities are complementary. -- Horst von Brand vonbrand@sleipnir.valparaiso.cl Casilla 9G, Viña del Mar, Chile +56 32 672616
