Fedora's elections are now open until Wednesday, 7th January!
I'm applying for a seat at FESCo [1] as I want to represent the interests of users, developers and maintainers of what we call Atomic, Bootable Container, Image Based or Immutable variants of Fedora (CoreOS, Atomic Desktops, IoT, bootc, etc.).
You can find my full interview at https://communityblog.fedoraproject.org/f43-fesco-elections-siosm/
And vote at https://elections.fedoraproject.org/
The recording of my third talk with Pragyan and Vitaly at All Systems Go! about UKI, composefs and remote attestation for Bootable Containers is now available: https://app.media.ccc.de/v/all-systems-go-2025-362-uki-composefs-and-remote-attestation-for-bootable-containers

The recording of my second talk at All Systems Go! about how we moved Fedora CoreOS to Bootable Containers is now available: https://app.media.ccc.de/v/all-systems-go-2025-375-leveraging-bootable-oci-images-in-fedora-coreos-and-rhel-coreos
While I'm the one doing the talk, all the credit goes to Jonathan Lebon who did most of the work mentioned there.

We are bringing UKI and strong boot integrity guarantees with composefs to Bootable Containers. We demonstrated our latest progress on that front at DevConf.cz 2025: https://pretalx.devconf.info/devconf-cz-2025/talk/739KGC/
Sean tells us about bootable containers and asks for our opinions on how he plans to use them with Kubernetes.
You can thank `bootc`, `/usr/lib/bootc/kargs.d/`, and @fiftydinar for your new ability to include kargs in your native container image.
Just make sure to update with `bootc` instead of `rpm-ostree`.
Check it out!

Ah yes, nothing screams productivity like spending countless hours installing 53 different panels and 27 docks just to make your terminal look like a circa-2001 GeoCities page. 😎 Meanwhile, your bootable containers are out there actually doing *real work,* but sure, let's focus on choosing *the perfect shade of blue* for your desktop. 🖌️

With Allison, I presented at FOSDEM how we can combine UKI, composefs and containers to build a fully signed boot chain. The slides and the recording are now available: https://fosdem.org/2025/schedule/event/fosdem-2025-5191--signed-sealed-and-delivered-with-ukis-and-composefs/
This is how we are planning to bring boot chain integrity to Bootable Containers.
This is a follow up on the initial work that we presented last year at @allsystemsgo: https://cfp.all-systems-go.io/all-systems-go-2024/talk/HVEZQQ/

There's a big new update to the BlueBuild CLI, with some real nice DX upgrades. Thanks @gmpinder 💙

Bootable Containers are the future of Fedora Atomic Desktops and we presented that at @allsystemsgo.
Introduction by @cgwalters and Ben: https://media.ccc.de/v/all-systems-go-2024-266-bootc-generating-an-ecosystem-around-bootable-oci-containers
Then take a look at how we could use sysext's to improve the local layering story with @tormath1: https://media.ccc.de/v/all-systems-go-2024-313-waiter-an-os-please-with-some-sysext-sprinkled-on-top
And then finally dive into Trusted Boot with UKI and composefs with @jbtrystram: https://media.ccc.de/v/all-systems-go-2024-309-the-road-to-a-trusted-and-measured-boot-chain-in-bootable-containers

To be more precise, the updates are #atomic, while most of the system is #immutable, that is a term with a certain meaning in programming languages but people not used to it think "can't be modified".
BTW the new term (specific to the current #FedoraAtomic / #CoreOS) may be #BootableContainers when they will migrate to #bootc and I think it makes very clear to many people that it brings all the advantages of the OCI ecosystem
I will definitely be taking a look at the new #ImageMode deployment method Red Hat announced yesterday during Summit. It has potential for some really cool applications and deployment cases. I'm thinking of spending some time this weekend messing around with generating @centos and @fedora images!
