2. Chrome OS / Chromium OS

Chromebooks use a robust AB scheme. Slot A is "Stable." Slot B might be "Beta" or "Recovery." Pressing Ctrl+Alt+Shift+Forward/Back on a Chromebook force-switches slots—a hidden gem for developers.

1. Mobile Devices (Android Seamless Update)

This is the most common implementation. It ensures that even if a critical system update has a bug or the battery dies during installation, the phone will always be able to boot into a working state.

Real‑World Example: Setting Up a Simple AB Multiboot on Linux

Note: This is an advanced DIY setup. For production, tools like RAUC (Robust Auto‑Update Controller) or swupdate handle AB logic automatically.

  1. Partition your disk

    • mmcblk0p1 – bootloader (e.g., U‑Boot)
    • mmcblk0p2 – Slot A rootfs
    • mmcblk0p3 – Slot B rootfs
    • mmcblk0p4 – shared data

  2. Install two identical OS copies
    Use dd or rsync to populate each slot.

  3. Set up a boot counter
    In the bootloader config (e.g., U‑Boot environment variables):

    boot_slot=A
try_count=3

    On each boot attempt, decrement try_count. If it reaches 0, mark slot bad and switch to the other.

  4. Mark success
    Add a systemd service that runs after successful login:

    fw_setenv boot_success 1   # persists success flag
