[Bug]: Artifact copy does gives the write owner

[taorepoara]

What happened?

I used a builder with specified user but when I copy artifacts to the builder they are always added for the user 1000.

Here is my Dofigen file:

builders:
  - name: copy-source
    from: alpine
    workdir: /app
    adds: [.]

      - ls -al

        - install_packages gettext-base
