Can someone tell me why #bootc is a replacement for #ostree? It seems like a solid downgrade.

Ostree has better download semantics, while bootc literally... clones container layers. Ostree lets you create temporary and permanent overlays. Bootc asks you to "maintain" your own container image. The temporary overlay solution is to use sysexts overlays, which is far more restrictive.

There are many other points that I'm forgetting right now.

So why is ostree being sunset in favour of bootc again?

#fedora #coreos #bootc #ostree #immutable #atomic #linux

@britter No, I do not.

Fedora Kinoite and U-Blue Aurora (and Fedora Silverblue ...) are based on container images. So when doing an upgrade or update, actually you are just jumping from one image version to another under the hood.

As they are immutable, most of the system is read-only. Which includes the root partition, so creating the `/nix` directory is not possible.

So my simple solution back in 2023 was to build my own container image that only creates that directory. During the image build this is still possible.

But now this fails, as the base image has too many layers already and docker runs into issues in the GitHub Action.

Hence I need to find another solution. Getting rid of the container image would be good, because why have a container image for just a directory...

J'ai préféré désinstaller tous les paquets ajoutés par #Flatpak de ma #Linux Fedora Kinoite pour les intégrer à #OSTree via la commande rpm-ostree.

🐧 Bootable Containers – Bare metal w świecie kontenerów

Adam Piaseczny opowie o #bootc i #OSTree – podejściu, które pozwala uruchamiać system #Linux z obrazów #OCI, aktualizować go przez CI i korzystać z bezpiecznych rollbacków. To technologia stojąca m.in. za projektami takimi jak Fedora Atomic czy Bazzite.

I'm judging distros by the ability to remediate #copyfail and anything #fedora #ostree based right now is failing hard. That applies to #bluefin and #bazzite transitively.

# rmmod algif_aead
rmmod: ERROR: Module algif_aead is builtin.

#nixos does not have this problem, I can rmmod there just fine.

Dear ostree users out there (on Fedora, RHEL, Bluefin, Aurora, Bazzite, ...),

has anyone of you ever seen an error regarding "invalid gzip headers" during a "rpm-ostree upgrade"?

[...]
[2/98] Fetching ostree chunk 53a115d85164231992f (46,2 MB)... done
error: Importing: Unencapsulating base: Layer sha256:53a115d85164231992fb38d82f836a36e9be489b15cfa415559419d164a7b6c0: Importing objects: invalid gzip header

I am building my own images to have the /nix directory available. Worked like a charm but suddenly stopped working for my Fedora43 image due to this error. The Aurora-with-nix image is fine, though.

Funnily enough, as my image only adds the nix directory, I only have one "custom" layer, everything else is from the upstream image. So I am puzzled on why this fails, why it fails for me and not for anybody/everybody else and why I do not find any issues related to "invalid gzip header" errors...

🐧Bootc and OSTree: Modernizing Linux System Deployment

「 OSTree is often described as “Git for filesystems”. It enables versioning, distribution, and atomic deployment of Linux systems. Rather than managing packages individually, OSTree stores complete system snapshots, making updates and rollbacks easier 」

Bootc and OSTree: Modernizing Linux System Deployment

Discover how Bootc and OSTree are revolutionizing Linux system deployment, offering modern, efficient, and immutable management.

Hey #linuxgamers.

I made a simple script to fix the Switch 2 Pro Controller over USB with steam input on OSTree distributions. I'm gonna also make a version for more normal distros but that's not a priority.

So TIL: one doesn't have to use Fedora CoreOS to get an atomic server-oriented system.

Instead of uCore, I can have my BlueBuild setup use quay.io/fedora/fedora-bootc or even quay.io/fedora/centos-bootc as the base image. I can then build an Anaconda installer ISO from this bootc image and install it the normal way instead of using ignition files.

Super cool!
