We use build-container-installer. Last I remember, that had no issues with creating ISOs that use bootc. Just uses a different command in anaconda. @Skynet would know the more technical details there.

Robert•8/15/24, 4:33 PM

We've been including bootc in bluefin for quite some time. So maybe that's resolved

Skynet•8/15/24, 4:33 PM

It works with bootc. I use it with bootc for my custom images

imbev•8/15/24, 4:33 PM

ostreecontainer is the anaconda command iirc. That's what I'm using in HeliumOS

NoelOP•8/15/24, 4:33 PM

We included bootc just in Bluefin right? Not in our main images because we are waiting on Fedora anyway?

antheas•8/15/24, 4:33 PM

Also, certain stuff from the base commit is used as is. This is SELinux and the directory structure with permissions

antheas•8/15/24, 4:34 PM

if the base image is too thin, you will get issues with both

Robert•8/15/24, 4:34 PM

What makes a bootc system a bootc system?
I can run bootc status and bootc update. But I can also run rpm-ostree status and rpm-ostree update

Does a bootc system look exactly the same as an rpm-ostree system?

Skynet•8/15/24, 4:35 PM

Bootc works similarly to rpm-ostree for some things, so there's a lot of commands that will work in both. The main thing I've noticed, is that bootc also allows dnf commands during the images build. I'm sure there's other things, but that's the main one I've noticed

antheas•8/15/24, 4:36 PM

i think thats due to dnf5 not erroring out

antheas•8/15/24, 4:36 PM

they somehow removed the error

imbev•8/15/24, 4:36 PM

Correct me if I'm wrong, bootc fetches from an OCI registry, while rpm-ostree interacts with dnf/ostree remotes

antheas•8/15/24, 4:36 PM

both bootc and rpm-ostree use ostree-rs-ext under the hood for OCI right now

antheas•8/15/24, 4:36 PM

so they're the same, just a different api

antheas•8/15/24, 4:36 PM

when the podman PR merges this will change

antheas•8/15/24, 4:37 PM

but then rpm-ostree will be refactored to use bootc (?)

antheas•8/15/24, 4:37 PM

so it will still be the same

Robert•8/15/24, 4:38 PM

I'm going to try adding dnf5 during the build and seeing what happens when I try and use it

NoelOP•8/15/24, 4:38 PM

So mostly the benefit of bootc is still in the future. We are waiting on podman and zstd chunked.

Which tooling creates the current ublue ostree commits?

Iimbev Which tooling creates the current ublue ostree commits?

Kyle Gospo•8/15/24, 4:43 PM

buildah & rpm-ostree

Kyle Gospo•8/15/24, 4:43 PM

and as long as bootc is in the image

Kyle Gospo•8/15/24, 4:43 PM

and you don't layer anything

Kyle Gospo•8/15/24, 4:44 PM

you can use bootc on any ublue image today

imbev•8/15/24, 4:44 PM

What I mean to ask is how are ublue images currently built? I see https://github.com/castrojo/ublue, but that appears to be no longer used?

KKyle Gospo you can use bootc on *any* ublue image *today*

Robert•8/15/24, 4:44 PM

If you use bootc on an existing ublue image, is it any different to an image where you started with bootc from the beginning?

How does rpm-ostree handle /etc?

antheas•8/15/24, 4:45 PM

it doesnt

antheas•8/15/24, 4:45 PM

ostree does

antheas•8/15/24, 4:45 PM

with a 3way merge before rebooting to the new deployment

antheas•8/15/24, 4:45 PM

new files and changed files remain

antheas•8/15/24, 4:45 PM

in the new image, and replace the new image's /etc

imbev•8/15/24, 4:46 PM

That behavior is shared by bootc

Iimbev That behavior is shared by bootc

Kyle Gospo•8/15/24, 4:46 PM

because bootc uses ostree

antheas•8/15/24, 4:46 PM

bootc is a thin layer over ostree so yes

Kyle Gospo•8/15/24, 4:46 PM

it's all ostree

NoelOP•8/15/24, 4:47 PM

All roads lead back to OSTree lol. I wish rpm-ostree was named something different. I got confused by that for the longest time.

antheas•8/15/24, 4:50 PM

the fedora bootc repo is kinda cursed imo

antheas•8/15/24, 4:50 PM

the way they build the base image is very complicated

imbev•8/15/24, 4:50 PM

Looking at https://github.com/ublue-os/main/blob/main/Containerfile, the install scripts will need to be replaced by bootc configuration such as https://gitlab.com/fedora/bootc/base-images/-/blob/main/tier-0/kernel.yaml for the base images, and regular dnf commands for downstream images
