说明
sulogin is invoked by init when the system enters single-user mode. It prompts for the root password and starts a root shell. This is used for system maintenance and recovery. The command is typically called automatically during boot when entering single-user or rescue mode. It provides secure access to the system when normal multi-user services are not running.
