The Late Night Linux FamilySean tells us about bootable containers and asks for our opinions on how he plans to use them with Kubernetes.
BlueBuildYou 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!

N-gated Hacker NewsAh 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. 🖌️

The Joy of Linux Theming in the Age of Bootable Containers
Having spent a couple of decades in the Linux world, I have always had an interest in Linux desktop environments and how they are themed. I would often come across a post on /r/unixporn that inspired me to try to customize the look and feel of my desktop environment. So I would install Xfce, LXQt or Sway and try to recreate components that I like from other users or create my own. I would end up installing different kinds of panels, plugins, docks and launchers as well as random themes, fonts and sounds.
Jörg KastningI'm really exited about RHEL image mode that offers a method to manage RHEL in a container native way.
If you like to know how what it has to offer checkout my tutorial at: https://developers.redhat.com/articles/2025/03/12/how-build-deploy-and-manage-image-mode-rhel
Kennt ihr den RHEL image mode? Es ist eine der spannendsten Neuerungen in RHEL. Mehr dazu könnt ihr in meinem Blog erfahren: https://www.my-it-brain.de/wordpress/einfuehrung-in-den-rhel-image-mode/
Timothée RavierWith 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/

Bootable Containers are the future of Fedora Atomic Desktops and we presented that at @allsystemsgo.

Bootc: Getting Started with Bootable Containers
Alex L 🕊 🇵🇸@Eeyore_Syndrome @LinuxRenaissance
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
