Instructions

1. Log in to servera as the student user.

   [student@workstation ~]$ ssh student@servera
   ...output omitted...
   [student@servera ~]$

2. Create the /home/student/kickstart.cfg file by copying the contents of the /root/anaconda-ks.cfg file using privileged access.

   [sudo] password for student: student

3. Make the following changes to the /home/student/kickstart.cfg file.

   1. Comment out the reboot command:

      #reboot

   2. Modify the repo commands to specify the classroom server's BaseOS and AppStream repositories:

      repo --name="BaseOS" --baseurl="http://classroom.example.com/content/rhel9.0/x86_64/dvd/BaseOS/"
      repo --name="Appstream" --baseurl="http://classroom.example.com/content/rhel9.0/x86_64/dvd/AppStream/"

   3. Modify the url command to specify the classroom server's HTTP installation source:

      url --url="http://classroom.example.com/content/rhel9.0/x86_64/dvd/"

   6. Modify the authselect command to set the sssd service as the identity and authentication source.

      authselect select sssd

   7. Modify the services command to disable and enable services.

      services --disabled="kdump,rhsmcertd" --enabled="sshd,rngd,chronyd"

   8. Comment out the part commands and add the autopart command:

      #part /boot/efi --fstype="efi" --size=100 --fsoptions="..."
      #part / --fstype="xfs
      autopart

   9. Delete all of the content between the %post section and its %end directive. Add the echo "Kickstarted on $(date)" >> /etc/issue line.

      %post --erroronfail
      echo "Kickstarted on $(date)" >> /etc/issue
