Executing Update and Rollback Using A/B Partition System

To modify or rollback Photon OS updates using A/B partition system, perform the following workflow:

1. Edit the files on the inactive partition set. You can use the command options like mount, update, and deploy to mount and edit the files based on your requirements.

2. Switch to an inactive partition set using the abupdate switch command.

3. If you are not satisfied with the update, execute abupdate switch or reboot to roll back to the old active partition set.

4. If you are satisfied with the update on the inactive partition set, finalize the switch with the abupdate finish command. Note: Once you execute the abupdate finish command, a reboot does not roll back to the previous partition set.
