I think it's important to recognize that we're trying to address an issue that has a much wider potential audience than pro audio users, and not very far off - what is high end audio performance today will be expected desktop performance next year. So I think it's critical that we find solution that's appropriate for _every single box_, because realistically vendors are going to ship with this "wholly self-contained" feature turned on by default next year, at which point the "containment" will be nil and whatever warts it has will be with us forever. The rlimit stuff is not perfect, but it's a much better fit for the UNIX model generally, which is a fairly big win. Having it in the system unconditionally doesn't trigger the gag reflex in quite the same way as the LSM approach. -- Mathematics is the supreme nostalgia of our time. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
