@cmccullough @centos @almalinux Try AlmaLinux. Stable, rock solid. Works like a charm.
(Or go immutable with #Fedora #CoreOS or #openSUSE #MicroOS)
I'm a Cockpit dev, anyone who uses Cockpit in Fedora Atomic who has any gotchas or frustrations?
About to spin up my own CoreOS server which made me wonder if anyone has issues due to ostree or bootc related stuff

This past week I went on The Self Hosted Show from Jupiter Broadcasting Studios to talk about @fedora CoreOS edition. Was great to chat with @ironicbadger, Brent Gervais and Chris Fisher, especially since it's been a few years since we were last able to catch up.
Check out the show!
Une fois n'est pas coutume, voici un toot en français ! J'ai été interviewé par des membres de la communauté française Fedora et ils ont publié l'interview sur linuxfr.org. J'y parle notamment de Fedora, Atomic Desktops, CoreOS et KDE.
C'est donc en français et c'est disponible ici : https://linuxfr.org/news/20-ans-de-fedora-fr-quatrieme-entretien-avec-timothee-contributeur-des-systemes-immuables-et-kde
The wonderful folks from the french speaking Fedora community have just published an interview with yours truly where we talk about Fedora, Atomic Desktops, CoreOS and KDE.
It's in french and you can find it on linuxfr.org: https://linuxfr.org/news/20-ans-de-fedora-fr-quatrieme-entretien-avec-timothee-contributeur-des-systemes-immuables-et-kde
I've completely reworked how I build the sysexts for Fedora Atomic Desktops, Fedora CoreOS and other image based Fedora systems.
We now have a pretty website listing them: https://extensions.fcos.fr
This is still an unofficial/experimental project but it has been working well for me for a while now.
Next step: writing a manager for all those sysexts to make installing/removing and updating them easier.
Hey @hetzner,
The folks at Fedora have done the work to make a Hetzner-specific image of CoreOS (see https://github.com/coreos/fedora-coreos-tracker/issues/1324).
When do you think we’ll be able to see it in this menu with a little lightning icon next to it?
Ball’s in your court now :)
Running Fedora CoreOS (FCOS) on Hetzner Cloud 
with a custom image and Ignition via user-data :-)
How To:
https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-hetzner/
Happy to see Fedora has implemented CoreOS support for Hetzner. Guess the ball’s in Hetzner’s court now: would be great to see it as one of the natively-supported operating systems with rapid deploy (under 10 seconds deployment).
Tomorrow 5pm UTC is the final go/no-go meeting for the release of Fedora Linux 42: https://calendar.fedoraproject.org/meeting/11013/?from_date=2025-04-07
If everything goes to plan, then the new release can be there as soon as 2025-04-15 !!
It's the first release of Fedora Linux, that will promote the KDE desktop to full "Edition" Status (Same as the Gnome Desktop variant).
I've already been running F42 KDE edition on my daily devices and didn't envounter any issues so far 
Also running some VServers with Fedora CoreOS 42 on Hetzner Cloud, which is also a joy to work with :-)
https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-hetzner/
Some upstream contributor’s have been hard at work and we now have a Hetzer Cloud downlaodable image and docs page for @fedora #CoreOS Nice work everyone! https://docs.fedoraproject.org/en-US/fedora-coreos/provisioning-hetzner/
I will be at #KubeCon / #CloudNativeCon in London this week.
I'll give a workshop on Wednesday with @tormath1 on how to use and build systemd system extensions (sysexts): https://kccnceu2025.sched.com/event/1tcxe/contribfest-extending-image-based-systems-using-systemd-system-extensions
Feel free to reach out if you want to chat about Fedora CoreOS and running Kubernetes on it, Openshift, Fedora Atomic Desktops, Flatpaks, KDE or anything else .

I had to refrain from calling "Bingo", because I had anticipated that question. But it is an obvious question that deserves an answer. I also had to stop myself from quoting Shakespeare ("There more things ...").
In my case it boils down to this:
1. I have been experimenting with using #NixOS on my laptop, where I do all of my (private) things. I also have home-manager on my work laptop.
I can almost do all of the things I can on my #openSUSE #Tumbleweed laptop. This includes packaging for openSUSE.
But I have not converted all of my 3 dozen different VMs, servers, raspis, NUCs and whatnot to NixOS. They will keep running a mixture of immutable (openSUSE #MicroOS, #Fedora #CoreOS, NixOS, ...) and non-immutable things (Debian, Proxmox, ...). And I would like to be able to manage them from whatever host I am currently working from. Hence I would like to have a working Ansible environment on my NixOS laptop to manage other machines with.
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/
I've tooted about this before and I'm still so much in love with #podman #quadlet that I'm doing it again. Just did the daily fearless podman auto-update on one of my home servers. This little machine is running 34 containers consuming ~5GB of RAM with virtually no maintenance necessary.
K8s and Proxmox have their use cases, but my homelab isn't one.
I'll be at FOSDEM this weekend! I'll be giving a talk with Allison on composefs and how it fits well for image based systems: https://fosdem.org/2025/schedule/event/fosdem-2025-5191--signed-sealed-and-delivered-with-ukis-and-composefs/
Feel free to reach out if you want to meet and chat about Fedora CoreOS, Atomic Desktops, sysexts, KDE or Flatpaks. I'll likely hang around the image-based, container or Rust dev rooms.
