Composer: Building OS images for any platform
summary
A web UI for creating reproducible OS images that pulls packages from Fedora/Red Hat and third parties, stores git-backed blueprints, and spits out qcow2 and VMDK and tar archives (tar usable for container imports) via lorax/welder. Blueprints list packages, modules, users and keys, support kickstart and cloud-init workflows, and commit changes before build. Demo boots the generated VM successfully, but Composer avoids post-boot configuration, initially deprioritizes container images, and aims for immutable, repeatable builds unless the blueprint is changed.
