note that ATM, there is only a per-slot post-install hook. But, we have a post per-installation post-install *handler*.
This means, the hook will be executed right after, e.g., your App image is copied and could be used to also write additional files you have in the bundle to the same slot (despite I would assume to have .db files in the datafs instead of appfs).

For copying DataFS content, you might want to join the discussion we have here:

https://github.com/rauc/rauc/issues/333

Maybe the discussion in https://github.com/rauc/rauc/issues/325 is also something that might be useful for your purposes.


Best regards, Enrico
