The 'bootable container' / 'native container' space is getting really exiting, even (and especially) for desktop usecases. Atomic Fedora has had support for so called Ostree Native Containers for a while now, and that will eventually adapt `bootc` as the base layer for building and booting containers (but as of now it's not totally ready yet). VanillaOS is also working on similar things but I don't think it'll use `bootc`.

Some awesome community projects have also been born out of this space:

- https://universal-blue.org/ provides some neat Fedora images, which have one of the best Nvidia driver experiences on Linux IME, and are over all solid and dependable

- https://blue-build.org/ makes it pretty easy to build images like Universal Blue's for personal use

The best part here is really the composability; you can take a solid atomic Linux base, add whatever you like, and ship it over the air to client computers with container registries. All clients see is a diff every day, which they pull and 'apply' to be used after the next boot.

There's also Elemental which is SUSE-oriented but distro agnostic https://github.com/rancher/elemental-toolkit

I've been hoping NixOS moves in this direction over time, the distribution/rollout aspect seems under-baked currently.

Something like this is what I had desired when briefly experimenting with Fedora CoreOS and having to build layered images for ZFS support. I was new to CoreOS and was stuck right after I finished building an OCI image. Eventually I learned that the only way forward was to boot with a base image, then layer what I had built and run `rpm-ostree commit`. I wonder if this project would've served my use case. The OCI ima…

uCore does this if you wanna check it out: https://github.com/ublue-os/ucore

What's the best way to start with Elemental today? I haven't been able to grasp a start point, unlike RKE/Rancher which is pretty easy to onboard.
