At this point, why not just build statically linked binaries of those utils in the build stage and just copy them over? Or even better, have a static build of busybox with all of the non-dependencies disabled. Those filename bytes add up fast!
On unrelated note, --chmod parameter of the COPY instruction provides a way to avoid additional layers just to set the executable bits:
# instead of
COPY ugit .
RUN chmod +x ugit && mv ugit /usr/local/bin/
COPY --from=builder /usr/local/bin/ugit /usr/bin/
# could just be this
COPY ugit --chmod=755 /usr/bin/
In all seriousness though, that Dockerfile is basically one big uglified red flag, please don't do this, people.
