     The first phase of upgrade has completed successfully:
       - created Upgrade Checkpoint 'rootfs-nmu-005'
       - the appliance is ready to reboot into this new checkpoint

   |                                                                  |
   |  At this point there are two options:                            |
   |                                                                  |
   |   - You can reboot now and make sure that system is healthy.     |
   |     You will be prompted to activate the newly created           |
   |     checkpoint after the reboot.                                 |
   |                                                                  |
   |   - Or, you can simply continue using the appliance as is and    |
   |     later activate this new checkpoint, and then reboot.         |
