Magisk Overlayfs

This is still Work-in-process

• Emulate your system partitions become read-write-able by using OverlayFS
• Make system partition (/system, /vendor, /product, /system_ext) become read-write.
• Use /data as upperdir for overlayfs (only support ext4 /data)
• All modifications to overlayfs partition will not be made directly, but will be stored in upperdir, so it is easy to revert.

Build

There is two way:

• Fork this repo and run github actions
• Run bash build.sh (On Linux/WSL)
