 The `busybox` executable is replaced by the [statically linked busybox](https://pkgs.alpinelinux.org/package/v3.16/main/x86_64/busybox-static) from `alpine:latest`.
-The Alpine project provides far more timely security patches to `busybox` that the official `busybox` release. No other parts of Alpine are needed or used in this image.
