Foreman, Katello and bootable containers
summary
Foreman and Katello act as the stable content and provisioning hub for bootable container workflows: images (CentOS Stream 10 example) contain 480 RPMs, 66 layers and ~1.7 GB versus 340 MB for minimal images, include kernel, systemd and bootc, and are built with Podman/Docker then converted by bootc image builder or installer tooling. Machines deploy via Anaconda/kickstart (OS3 container) or raw DD, update atomically with A/B partitioning for safe rollbacks, and Foreman tracks image digests, staged upgrades and bulk operations.
