See system logs and > 'systemctl status remount-rootfs.service' for details. These are just units where other units try to order against, but which are not available. It's nothing wrong here, besides the misguiding output, which we should think about what to tell instead. Could you add: systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M to the kernel command line? It will print all userspace log to the kernel buffer, which is the most reliable way to store the logs when stuff goes wrong that early during bootup. It should tell us more what's going on, and why you end up in the rescue shell.
