If we log to the pty that is configured as stdin/stdout/stderr of the container too early we risk filling it up in full before we start processing the pty from the parent process, resulting in deadlocks. Let's hence keep a copy of the original tty we were started on before setting up stdin/stdout/stderr, so that we can log to it, and keep using it as long as we can. Since the kernel's pty internal buffer is pretty small this actually triggered deadlocks when we debug logged at lot from nspawn's child processes, see: https://github.com/systemd/systemd/pull/9024#issuecomment-390403674 With this change we won't use the pty at all, only the actual payload we start will, and hence we won't deadlock on it, ever.
