Day 2 of #hackdays2025: #EU_OS has now a new Proof-of-Concept section on the website (work in progress). The team enrolled some #bootc machines in #Foreman. The results so far were pitched to a selection board. Thanks to the great team who made this all possible! 
Unfortunately, #EU_OS has not been selected to proceed to the next stage.
@escapetofreedom @eu_os @opensuse
Please check out https://eu-os.eu/faq#fedora
#opensuse does not support #bootc so far. Otherwise EU OS proof of concept is agnostic to the distro.
Finally! It seems that both bootc + rpm-ostree in Fedora 42 know how to handle zstd:chunked OCI bundles.
So both the improved compression by the Zstandard algorithm AND it's inherent capability to produce a segmented output stream that is a series of compressed files with embedded metadata, which can be deduplicated over the network (!), are supported.
Perfect addition to OSTree chunks, which are small, grouped blobs (e.g. pairs of metadata and one or more packages).
6 days until #EU_OS at Paris #HackDays: EU OS is a so-called atomic operating system that offers interruption free software updates thanks to #bootc (bootable container) technology. While people work, bootc downloads and installs unnoticeable to the user the update. After the next computer restart (trigged by the user), EU OS switches to the new version. If something breaks, the user can roll back. 1/2
Dear @debby ,
can you please check out first our FAQ at https://eu-os.eu/faq#sovereignty
So far, #LinuxMint does not support #bootc, which EU OS relies on to enable collaboration through sharing of container layers.
I recommend you read https://blues.win/posts/joy-of-linux-theming/ that poses the very relevant question: "what is a Linux distribution anyway"?
So if EU OS is a distribution by itself pretty much depends on the definition of distribution. I think the definition should be narrow and then #EU_OS should would not be a distribution.
WOW I didn't realize I am already using #Bootc and #ComposeFS on my system.
Thanks #uBlue #AuroraLinux
Now let's check the status of #Podman + ComposeFS...
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!

plz: #EU_OS is now partner for the French Gov Hack days early June in Paris.
The organisers were so kind to create a dedicated track covering the OS part of the digital workspace.
Check out the call for participants to join the EU OS team in Paris (or online):

new fyra this week just dropped (for the first time)
https://blog.fyralabs.com/fyra-this-week-1/
#tech #linux #foss #fyralabs #ultramarinelinux #bootc #wsl #fedora
https://eu-os.gitlab.io received a few updates today after some legit criticism.
- Logo has now consistently a purple gradient for more distinction to EU flag 
.
- Home page: EU OS is not yet an EU project
- FAQs acknowledge that Linux is already used in the public sector. The unique selling point is better clarified: use of #bootc and more collaboration across the EU to bring down the costs for a migration from Windows #endof10
- university of Oslo added to use cases

The Universal Blue team was tired of waiting for upstream so we did it ourselves and made a Live ISO builder for `bootc` images: Titanoboa! It's currently in a pretty alpha-ish state since we've started developing this like 3 days ago, but its already somewhat functional and Blue95 (a custom windows95-like image made by Adam Ledif) already has a functioning live installer for the image if you wanna try it out!
What does this mean for you? Faster, smaller, and more accessible installation environments :)

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. :)
To my knowledge #opensuse is not yet available as images with rpm-ostree layer. Though I think this development and #bootc are big advantage for organisations who already work with containers. It is also an advantage for organisations that would require more than one image for different ministries/departments/user groups.
I have followed the development on #MicroOS and @kalpa . It was still beta last time I checked. It works differently.
NixOS is cool, but it's nothing new. I've seen many smart people doing an excellent job with chroot, symlinks, and Chef/Puppet long before NixOS came along. A really cool thing is the Atomic desktop and bootc model. If you want a secure and solid environment, the Atomic desktop is the way to go. There's a learning curve, but it opens up a whole new world for you. #nixos #atomicdesktop #bootc
Attention opensource #OS developers, this one's for you!
Got something to say about #Linux-based operating systems? #DevConf_CZ is looking for speakers to share insights on @fedora Linux, @centos Stream, RHEL, CoreOS and Silverblue, or maybe new technologies and features such as bootc, immutable systems, dnf5, Konflux, edge, and automotive.

#Podman is already one step further with #Bootc and soon one more with #ComposeFS ;-)
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!
