With the addition of ancillary scripts like `entrypoint.sh`, the `COPY .` instruction in the build stage results in a full rebuild of the final image for every change. To avoid this, we now only copy the files that are actually required to build the wheel. The other scripts are copied later, using an intermediate layer. This avoids needing a `COPY` instruction, and therefore a new layer in the final image, for each script. Hypothetically, we could use `RUN --mount=bind` and copy the files with the `install` command, but bind-mounting the build context doesn't actually work; SELinux prevents the container builder from accessing the source directory directly.
