backend-utils container mounts some files in the already mounted volume

[Tiendil]

      - ${PWD}/ffun:/repository
      - ${PWD}/.env:/repository/.env
      - ${PWD}/changes:/repository/changes
      - ${PWD}/CHANGELOG.md:/repository/CHANGELOG.md

It leads to creating empty .env and CHANGELOG.md files in the ./ffun directory. Currently, they are added to .gitignore, but it will be good to somehow improve the development environment to remove such "recursive" mounting.
