Julius: pong The main two problems that I see in the existing interface are a) lack of extendibility (which is why we are here) and; b) non-idempotent actions, especially adding and deleting real servers, which mean that user-space programs that manipulate ipvsadm have have extra (racy) logic. (ok, perhaps that is more a pet peeve than a problem). I don't really have any concrete ideas about what a better interface would look like. But I am more than happy to hash our ideas. -- Horms -- To unsubscribe from this list: send the line "unsubscribe lvs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
