CompTIA Linux+ XK0-006 (V8) Practice Question

After cloning a Debian-based server to a replacement disk, the first reboot halts with an initramfs emergency prompt reporting that the kernel cannot mount the root filesystem on the UUID supplied in the root= parameter. Investigation shows that GRUB2 (installed in legacy BIOS/MBR mode) is still passing the old UUID to the kernel. The administrator wants to make the new root UUID persist across future kernel updates. Which configuration file should be modified before running update-grub so the correct root= value is passed to the kernel at every boot?

  • /etc/default/grub

  • /etc/fstab

  • /etc/grub.d/40_custom

  • /boot/grub/grub.cfg
