Hi,
many thanks for your request. Well, it’s a BETA image and basically it’s a question to ask to Raspberry Pi Foundation. They are providing the base image. But we already know that there are challenges and some thinks not working as on the 32bit image
You can have a look to our GitHub post. https://github.com/MichaIng/DietPi/issues/3570
There we have thinks listed not working yet.
Personally I would not use it for production usage. To many thinks are still open by the Foundation.
btw the version of DietPi (current 6.32.2) has nothing to do with the underlying image. It just detect the image and act accordingly.
