I want multiple inheritance for dockerfiles. You know take an image with Rust and one with Xyce and a vsc devcontainer and just smash them together.


You kinda can with `FROM <image> AS <name>` and `COPY --from=<name>`

@kc8apf @pepijndevos This is such a great feature when building images. It's not really smashing them together though, it allows you to use multiple base images for the construction of a new one.

A crude approach to smashing together would be using your suggestion to copy over / and guessing it will work 🤣
