    When you’re on A, updates go to B. When you’re on B, updates go to A.

    After an update, a reboot will switch slots.

      Looks bad in comparison with Silverblue where I can pin many previous version. Thanks to OSTree, you can downgrade to any point in the history or even switch back to an older release.

        If OSTree suits you better, that’s fine!

        The A/B Partition method and OSTree are both great, but have different strengths

        VanillaOS described it in their FAQ once:

        Vanilla OS uses an A/B structure (ABRoot), which transacts updates atomically between two root micro partitions. The benefits of this system are the guarantee that the system is altered only when the entire transaction is successful (concept of atomicity), furthermore, the double root partition structure allows you to roll back to the previous state, directly from your boot, you will always have a home to come back to.

        This structure, unlike others, is compatible with already existing distributions and does not require a complex setup and allows easy re-initialization of the system without data loss.

        The 40gb total are both already reserved, and a normal user isn’t supposed to modify it so it shouldn’t fill up.

        For desktop apps, Vanilla will primarily stick to Flatpaks, so Firefox will also be a Flatpak.

        VanillaOS already has a custom boot menu that can be used to switch slots in case an update went wrong, so that you can go back to your older, but working system.

        The partitions are also not synced.

        If you install something using abroot (e.g an update) it will only be installed to the unused slot. So if you run abroot --update or use the included updater, and you’re in Slot A, it’ll modify Slot B, and vice versa.
