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.

I think I get the idea of Fedora Atomic (Silverblue, Kionite, etc.), but I do not get what uBlue is about.

Are those just another "ooh it's distro X but with preinstalled Y" or are those some soft of overlays on top of Fedora? Can't they just be some install scripts? Why not just base Fedora Silverblue? Maybe I don't get the idea, because people seem hyped.

Yes, all their images are purposefully normal fedora atomic images with stuff tacked on top. Some of that stuff comes in just scripts to make management a bit easier, some of it comes in the form of utilities like distrobox. They also come with zfs or proprietary Nvidia drivers or other things so you don’t have to manage them yourself, alongside tailscale and rpmfusion for nonfree stuff (like codecs). Some of them also have some light configurations, some of them have heavier configurations (especially in the case of bazzite).

You can totally do everything ublue does from a stock Fedora atomic image. Ublue just makes it a little more convenient. A sort of “oh, well I was going to do that anyway”.

Here’s the base dockerfile. As you can see, it confirms all of the above.
