rtcd: syscall::openat(0, '/scheme/sys/update_time_offset') used fd 0 (stdin) instead of the namespace fd, causing EACCES. Fixed by using libredox::call::getns(). acpid: AmlPhysMemHandler captured pci_fd at construction as Arc<Option<Fd>>, so after set_pci_fd() stored the fd, the handler never saw it. Changed to Arc<RwLock<Option<Fd>>> shared between AcpiContext and the handler. Base fork commits: 770694d0 (rtcd), 84573feb (acpid)
