: It often employs overlay filesystems , which allow for a read-only base image to be "layered" with a writable area. This ensures system stability while allowing user-made changes to persist.
This reduces storage from ~4GB to ~1.2GB and allows factory reset by deleting upperdir.
AOW RootFS uses the following Linux namespaces: | Namespace | Purpose | |-----------|---------| | Mount | Isolate /system, /data from host | | PID | Android processes see PID 1 as container init | | Network | Virtual bridge or host network (macvlan) | | UTS | Set hostname to “android” | | IPC | Separate System V / POSIX message queues | | User | Map container UIDs (0→100000) for security |

The key differentiator of AOW is integration:
: The term was also associated with Microsoft's early Project Astoria , a discontinued bridge designed to run Android apps on Windows 10 Mobile. Common Issues & Management
Why? Security and stability. A corrupted system app cannot brick the AOW instance because Windows can simply discard the overlay and reboot the rootfs.
