One can even bind special operations to both the ptmx node and slave nodes, to bypass most of the character device and tty dispatch. That might require too much hacking at the tty core to be worth it, though. -hpa _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
