   #   0 - halt (Do NOT set initdefault to this)
   #   1 - Single user mode
   #   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
   #   3 - Full multiuser mode
   #   4 - unused
   #   5 - X11
   #   6 - reboot (Do NOT set initdefault to this)
   #
   id:1:initdefault:              <-- Change this row.

3. Restart in single-user mode.

   # shutdown -r now <Enter>

4. Execute the uninstall.

   Start the network interface, and then execute bdpp_devuninstall.

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

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

   Return to the default run level that was recorded in Step 2.

   # Default runlevel. The runlevels used are:  
   #   0 - halt (Do NOT set initdefault to this)
   #   1 - Single user mode
   #   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
   #   3 - Full multiuser mode
   #   4 - unused
   #   5 - X11
   #   6 - reboot (Do NOT set initdefault to this)
   #
   id:5:initdefault:              <-- Change this row back to the original setting.
