ISO for Live USB images

When I booted Live USB built with Fedora Media Writer, I realized that it is missing about 1Gb of updates. While trying to upgrade the image, I’ve out of space on / filesystem, which I presume was in memory Updating Live image · Issue #527 · FedoraQt/MediaWriter · GitHub

So I thought why Fedora 36 image downloads for Media Writer are not updated?

Media Writer downloads ISO images. And ISO image is a CD format that needs specialized tools to create. It is not .zip or .tar, so you can not just update it with new files. So why use ISO format for distributing Fedora images?

My laptop is 7 years old and it doesn’t have a CD. And I don’t need it, actually, because I have USB.

Wikipedia says that Live CD (CD?) images are using SquashFS - Wikipedia. Why not just use SquashFS images directly? Why not to keep SquashFS images current with the latest updates? Is it possible to update the image used for Live USB without booting it on a real hardware?

Why using ISO in 2022 and not some ostree? Why this technology is not feasible - have a downloadabl Live USB image which is updated by standard dnf update call on a daily basis?

The image on the Download Fedora Workstation site represents the state of Fedora on the release date which is May 2022 for Fedora 36. You can use more up-to-date images from the Respins SIG:


That’s just awesome. Thanks.

I wish the workstation image could be directly visible from official download page.
