I haven't really been digging very deeply into this, but how do you make sure that you have the most up-to-date buildroot in the Docker image you use? If you're building for e.g. rawhide, you'd basically need to rebuild the image every time a package from minimal buildroot gets version/release bump. So IIUC you'd either have to rebuild the base image pretty often or you'd have to do "yum update" inside the docker image before you actually start building. At that point, I'm not really sure how much faster docker is.
Also, IIUC you require "yum" to be present in the docker image, which will probably draw in some dependencies that are unnecessary and may be unwanted (e.g. for Fedora builds).
Please correct me if I'm wrong.
