    We also have a GUI for trying this out!

    https://github.com/podman-desktop/extension-bootc

    We’re also starting to see other projects adopt a “OS as a Container image” such as Bazzite: https://bazzite.gg/ using bootc :)

    Feel free to ask any questions!

    You can also achieve this with your current system

    > nix-build '<nixpkgs/nixos>' -A vm -I nixpkgs=channel:nixos-25.05 -I nixos-config=./configuration.nix

    I use nixos btw

      Can this do vmdk format?

        I don't know the answer using the built-in VM attributes (I mean I'd guess probably, but I don't know how if so) but there's always nixos-generators for making VM images. Definitely used this for deploying VMs to cloud providers, haven't tried the VMWare one yet though.

    Huh, this is kinda wild. So for esxi images, this would seem to beat/potentially be simpler than the traditional Packer + interacting with an ISO on esxi infra, yes?

    > A container for deploying bootable container images.

    ...as long as the images are in the Red Hat family (Fedora, CentOS Stream, RHEL).

    Does bootc-image-builder build Native Containers?

    Do Native Containers work as VM images that can be stored in an OCI Image/Artifact/Package Registry?

    I've been mentioning Native Containers since I realized that was how bazzite works now.

    Is vagrant necessary anymore if host, vm, and container images can all be signed and stored in an OCI Image store?

    From https://news.ycombinator.com/item?id=44137501 re: Firecracker and Microsandbox VMs :

    ublue-os/image-template: https://github.com/ublue-os/image-template :

    > Build your own custom Universal Blue Image

    ublue-os/akmods has nvidia GPU drivers, nvidia-open, zfs: https://github.com/ublue-os/akmods :

    > A caching layer for pre-built Fedora akmod RPMs

    > OCI images providing a set of cached kernel RPMs and extra kernel modules to Universal Blue images. Used for better hardware support and consistent build process.

    nvidia-container-toolkit (CDI) is necessary for --gpus=all to do CUDA and libEGL 3D with podman. Is this also already installed in bazzite?

    ublue-os/devcontainer .devcontainer/devcontainer.json: https://github.com/ublue-os/devcontainer/blob/main/src/base/...

    It looks like the Just Justfile 40-nvidia.just has moved due to image topology simplification? https://news.ycombinator.com/item?id=39364975 :

    > ublue-os/config//build/ublue-os-just/40-nvidia.just defines the `ujust configure-nvidia` and `ujust toggle-nvk` commands

      What does "native containers" mean in this context?
