The kernel event scheme now implements kdup, so dup() of an epoll fd works and tokio's registry.try_clone() succeeds — fixing the tokio runtime EINVAL that killed every zbus daemon and the brush login shell. build-redbear.sh: gate the userspace build/sysroot clean on relibc/base (the forks userspace links) instead of any low-level fork, so a kernel-only change rebuilds the kernel + initfs + image without a full userspace re-cook.
