CompTIA Linux+ XK0-006 (V8) Practice Question

During an onsite troubleshooting session, you discover that a RHEL-based server never reaches the login prompt because systemd crashes immediately after it is started. You need to obtain a root shell as early as possible so you can inspect and repair the broken service files. From the GRUB 2 menu you press e to edit the boot entry. Which single kernel command-line parameter should you append to the line that begins with linux so that the kernel starts /bin/bash as PID 1 instead of the normal init system, giving you an immediate shell before any init scripts or systemd units are processed?

  • rd.break

  • init=/bin/bash

  • single

  • systemd.unit=rescue.target
