Bootc as a project is one with tons of promise and lots of community support. It's what is powering the next generation of Atomic Desktops, CoreOS, and Fedora IoT, not to mention all of the work that @UniversalBlue has done to show off everything that can be done today.

If you want to follow bootc more closely, regular updates from Fedora's end are shared here. :)

3 blog posts in 3 days, that's a record for me. (Sometimes I post twice a year!)

I guess I'm excited about bootc.

#Fedora (and #CentOS) #bootc image does not allow me to add the user to the group 'users'. But the group exists somehow, just not in:

```
$ cat /etc/group | grep users
```

What am I missing?

This is not an issue on the fedora container images:

```
$ cat /etc/group | grep users
users:x:100:
```

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/

Going to @socallinuxexpo ? Find me at the https://cncf.io booth to come learn more about cloud native!

Oh and I'll have this lovely piece of kit from #Framework -- running the latest Bluefin prototype, based on CentOS Stream 10. Try it yourself, on _proper_ metal.

I will have a special run of Achillobator stickers, limited quantities so set yourself a reminder!

Fedora 41 did not see big changes for Fedora Atomic Desktops, but we are certainly ramping up for the switch to bootc and being fully image-based!

Learn more about what's new for Fedora Atomic Desktops and what is coming for Fedora 42!

If #FedoraAtomic ends up adopting #bootc with release *42* I will consider it a good omen in favor of bootable containers

Hello from Ultramarine on bootc!

(Ultramarine Atomic GNOME 41, development build) #tech #fedora #bootc #atomic #immutable #immutablelinux #ultramarine #ultramarinelinux #foss #linux

Catch the episode on bootable containers from the Fedora Podcast! Will be live streamed today at 5pm EDT.

This will be all about bootc and how it expands on the atomic model that we see in Fedora Atomic Desktops , Fedora IoT, and Fedora CoreOS. Won't be the last time you hear about this!

I recently checked out bootable containers to try and build an immutable Kodi box and a CI runner machine. Very impressed with how it all worked out!

You know how with Fedora Atomic Desktops and Fedora CoreOS you can rebase to other images with rpm-ostree? With that you need to have an rpm-ostree system to start and then rebasing becomes available to you.

What if you could do the same starting from a regular Linux system and migrating to an atomic one? That's one feature being explored with bootc that Ben Breard talks about in this video!

Update: Show will be rescheduled due to conflicts

Join us today at 5pm EDT (9pm UTC) for an update on the atomic world of Fedora on the Fedora Podcast! @siosm will be explaining what bootc is, how it relates to rpm-ostree, and how it relates to the *future of desktop Linux.*

Hint: image-based

Livestream: https://www.youtube.com/watch?v=zF7aTCoWoLQ

Bootc is basically the next generation of rpm-ostree. Here's an early look at bootc from someone who happened to start looking into Fedora CoreOS at the same time as bootc was announced. It's an organic exploration of both!

I feel like not enough people fully grasp how awesome Image Mode RHEL and bootc are. Seriously this is next Gen awesome and I think will become foundational to how immutable/atomic Linux distros are built in the next few years. SO COOL.

Introducing image mode for Red Hat Enterprise Linux

Image mode for Red Hat Enterprise Linux is a new deployment method that takes a container-native approach to deliver the OS as a bootc container image.
