Ensure authentication required for single user mode

SrednjaNivo 1Automatskaros

Opis

Single user mode is used for recovery when the system detects an issue during boot or by manual selection from the bootloader. The audit requires the root account to have a password set in /etc/shadow, so single-user mode asks for it. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.
