   #   4 - unused
   #   5 - X11
   #   6 - reboot (Do NOT set initdefault to this)
   #
   id:1:initdefault:            <-- Change this row.

4. Reboot in single user mode.

   # shutdown -r now <Enter>

5. Execute the uninstall.

   Start the network interface, and then execute bdpp_coouninstall.

   # /etc/init.d/network start  <Enter>
   # /opt/FJSVbdpp/agent/bdpp_coouninstall <Enter>

6. Change the default run level at system startup back to the original setting.

   Return to the default run level that was recorded in Step 3.
