OCI images that you can turn into a full-fledged developer workstation shipping Devbox, Nix, Homebrew, devcontainers and DevPod with one command. Pretty swanky!

Can someone ELI5 why this is so great? I watched the video and I hardly get it. (Linux user for 18 years)

Because it uses OCI images, it auto-updates like a Chromebook, and you can switch between modes, like say a gaming mode that's a full SteamOS replacement, to a mode that gives you an entire development environment without needing to install and configure these layers or stacks of capabilities yourself.

That's very powerful. For cloud native developers like myself who are used to working with container images as the deliverable artifact, this makes that workflow very easy. Podman is included. You can create entire development environments at will that are totally "pure": no side effects because everything you need is in the container. That's a Dev Container.

I'm still having a hard time grasping this, probably because I don't understand OCI images. How would this be different than say using fedora with docker to spin up containers with stuff I need?

Hmm, well Fedora on its own (so no Silverblue) is very much your classic way of shipping a distro. That tends to mean that, over time, "cruft" accumulates as you upgrade your system, uninstall/reinstall packages, etc. They leave bits of themselves behind that can cause unwanted behavior.

Fedora Silverblue, that Bluefin is based on, treats the entire system layer as "immutable". Basically, it ensures consistency so that upgrades and package upgrades don't leave the system in an inconsistent state.

What Bluefin adds on top of this is a set of opinionated, pre-configured layers suited for getting particular groups of tasks done. Those layers are also immutable and tested as a whole, which makes shipping those layers at velocity easy (faster upgrades, less wonky behavior on upgrade) and easy to swap between, so you can go from gaming to developer mode without worrying about an accumulation of cruft.

Is that helpful at all? There's also this announcement blog post, which I found very helpful in understanding the value proposition.

Yes!! Super helpful. Thank you!

Pretty much the same however it would be like you're working inside a docker container to cover and build your container images.

In this setup your entire os is a container also. It's just another layer. This is the same way the Steam Deck distributes updates and many of us believe to be the future for the next wave of Linux users.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
