ln -s will fail the image build if /usr/local/bin/python already exists (e.g., if the upstream base image or a future layer introduces it). Consider making this idempotent (e.g., conditional creation or forcing/replacing the link) so rebuilds remain robust while still ensuring python resolves to python3.
