Many thanks for reporting.

From where did you get an image that is not usr-merged? This is mandatory for Debian Bookworm, so all Bookworm images should be usr-merged, or considered as broken. All official Armbian images are definitely usr-merged.

Thank you for quick response.

It was official image: docker pull apache/airflow:2.7.2-python3.9

I've just tried with the latest 2.8.2. It's completely ok.

@MichaIng Thank you a lot.

Are you sure you are answering to the right issue? This Docker image does not use DietPi, but a Debian-based minimal Python image. And I can only hope that no one is trying to run the DietPi installer within a Docker container forged to serve a particular single application 😄.

Anyway, marking this as closed, as OP did not respond.
