Reproducible, Immutable, Bootable: Exploring bootc with Podman Desktop
summary
Claim: bootc turns an OCI image into a reproducible, immutable, bootable OS and Podman Desktop adds a cross‑platform UI + extension that builds, runs and publishes those artifacts. Demonstration builds a Fedora‑core bootc image that embeds a specific Gitea version, uses Podman Desktop’s Bootable Containers extension and bootc image‑builder to emit a raw disk, boots it on macOS hypervisor, shows SSH access and a running service, then does an atomic update and a clean rollback (reboot is the only downtime).
