Upgrading and maintaining AutoSD with OSTree

OSTree is a core technology that manages immutable AutoSD images using a content-addressed repository. Each unique version of an image is stored as a commit ID, similar to how Git tracks code versions. Version control enables atomic updates, ensuring that a system is either fully updated or remains on the previous version, thereby preventing partial or corrupted installations.

For environments with limited or no network access, AutoSD supports offline updates. Offline updates rely on static deltas, which are small files that contain only the changes between two specific image versions. Static deltas reduce the size of the update, which makes it possible to store deltas locally and apply them manually without an internet connection.
