systemd-nspawn creates a pty outside the container, but then bind-mounts
it onto /dev/console inside the container. Maybe that would be another
possibility? However, that only works if /dev/console already exists in
the chroot (it doesn't have to be a device node, it can just be an empty
file), and in a debootstrap-created minimal chroot, it doesn't.
