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!
I've always been hesitant to use this method over debootstrap: the Ubuntu container images ("FROM ubuntu:20.04") are created from a tarball that Ubuntu's convoluted CI system spits out and I'm not confident I understand if it's somehow suitable only for a container and not for real hardware.

However beware that they break backwards compatibility almost every 6 months. This is probably the most backwards-incompable project I know, you can't rely that the minor version update won't break your projects.
> nix-build '<nixpkgs/nixos>' -A vm -I nixpkgs=channel:nixos-25.05 -I nixos-config=./configuration.nix
I use nixos btw
`nixos-rebuild build-image --image-variant vmware`
See https://nixos.org/manual/nixos/stable/#sec-image-nixos-rebui...
What I like about this is always having a known working image I can quickly swap to, particularly for the machine with an nvidia card.
I've used this to start from a minimal base and added what I've needed on top. Best of all, updates are delivered via a container registry.
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?

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

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

From https://coreos.github.io/rpm-ostree/container/#ostree-native... :
> rpm-ostree inherits work in ostree-rs-ext to create “container native ostree” functionality. This elevates OCI/docker containers to be natively supported as a transport mechanism for bootable operating systems.
I think it means simplification of complexity and unnecessary re-duplication.
Does anyone have experience worth sharing with both?
Also, bootc is a basis for the Universal Blue family of distros, especially Bazzite, which is very popular with gamers.
I thought of the underlying tech for those other distros being ostree more than anything but this is the better interpretation.
...as long as the images are in the Red Hat family (Fedora, CentOS Stream, RHEL).
