@xxinran the parameter rwDev/roDir/rwDir is designed for container layers, not for image layers, so we didn't consider what happens when image pulling.
I tried rwDev and prefetching worked. you may checkout the overlaybd log (by default /var/log/overlaybd.log) to verify it.
If prefetching worked, "Prefetch: run with mode 2" and "Prefetch: Reload XXXX records" can be found in log.
"Prefetch: run with mode 1" means record mode which recording traces.
"Prefetch: run with mode 1" means prefetching is disabled.

@liulanzheng Thanks for your explanation, I also verified prefetching in my environment and it works.
As for 'rwDev' mode snapshotter fails to pull image with accel-layer, I have a fix here #117, comments are welcomed.
