Anything comparable to Docker multi-stage builds for LXD?

Anything like Docker multi-stage builds for LXD ?

Want to build something based on existing images, save the results, then apply those results to a pristine image.

distrobuilder looks like a tool where this could possibly be done ? Anyway to accomplish something similar ?

You could create an initial image from an existing instance using lxc publish and then create a new instance from that image, modify it an lxc publish it again as a different image.

If you’re talking about compiling something using one image type and then copying the result into another instance based on a different image type, you could use lxc file copy to copy files from one instance to the host and then into another instance.
