ou should be able to: $$ Diagnose issues and recover the system from emergency mode. $$ Change the default target from graphical.target to multi$-$user.target. $$ Schedule recurring jobs to run as a normal user. BEFORE YOU BEGIN Copy any files or work you wish to keep to other systems before resetting. Reset the workstation, servera, and serverb systems now. Log in to workstation as student using student as the password. On workstation, run lab rhcsa$-$compreview$1$ start to start the comprehensive review. This script creates the necessary files to set up the environment correctly. $[$student@workstation ~$]$$ lab rhcsa$-$compreview$1$ start INSTRUCTIONS Perform the following tasks on serverb to complete the comprehensive review: $$ On workstation, run the lab rhcsa$-$compreview$1$ break$1$ command. This break script causes the boot process to fail on serverb. It also sets a longer timeout on the GRUB$2$ menu to help interrupt the boot process, and reboots serverb. Troubleshoot the possible cause and repair the boot failure. The fix must ensure that serverb reboots without intervention. Use redhat as the password of the superuser, when required. $$ On workstation, run the lab rhcsa$-$compreview$1$ break$2$ command. This break script causes the default target to switch from the multi$-$user target to the graphical target on serverb. It also sets a longer timeout for the GRUB$2$ menu to help interrupt the boot process, and reboots serverb. On serverb, fix the default target to use the multi$-$user target. The default target settings must persist after reboot without manual intervention. Use the sudo command, as the student user with student as the password, for performing privileged commands.
