busybox should install links in CBL-Mariner's debug distroless images
The debug flavor of CBL-Mariner's distroless images ships busybox arguably to support interactive debugging.
However, links aren't installed in PATH so users can only use the image if they know how to call Busybox's functions (e.g., run -it ... 'busybox' 'sh' instead of the arguably more expected and natural run -it ... '/bin/sh')
One way to address this is to run busybox --install when creating the image. This is what's done in docker-library/busybox. Or perhaps declaring the appropriate ENTRYPOINT.
It's also possible this is by-design, but I couldn't find a reference to busybox install in Issues so it might be good to document it.
This definitely threw me off.
I was about to open a bug for the debug flavour before I found this issue.
