How to create an image from Bazzite? What am I missing?

Thanks for all the documentation. I've been poking through it, I feel like I'm missing something on this page:

https://blue-build.org/learn/universal-blue/

I want to build an image with bazzite (fairly minimal changes in mind currently, emacs, some fonts, maybe a few other things).

It's just not really clear how I'd go from bazzite to getting a custom image. I get to: Installing an image based on Universal Blue

But then it seems like it skips down to already having a custom image to install? It is a bit confusing to me because it seems like all of the commands refer to a fake image: ghcr.io/octocat/weird-os

Just feels like I'm going from step 1 to step 3.

Awesome thanks. So I start with the unsigned image and then add my changes?

Then I generate the new image?

If you want an example of a custom Bazzite image using blue-build, you can check out my custom image based on ghcr.io/ublue-os/bazzite-nvidia-open: https://github.com/yegua-labs/bazzua.

Many thanks for the follow up, I ended up getting what I needed with a sysext. I believe in the docs it says universal blue images wouldn't build for free on github.

At some point, I need to write a script for my brew stuff and the sysext stuff in case I need to get the image setup in the future (a new machine possibly).

I believe in the docs it says universal blue images wouldn't build for free on github.

Where does it say that? Everything builds for free on github, the only thing that isn't free is hosting offline ISOs.
