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.

Can someone explain Universal Blue (and images based on it) to me? (discuss.tchncs.de)

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.

It's a good question.

Fedor does not provide an image for every DE/wm. Anyone can create a custom atomic fedora variant with the desired de.

Moreover, you can create your own image and deploy it to 100 machines and all of them will have the exact same os and packages. This may not be useful for you as an end user directly but the dev who is developing the image for you (e.g. fedora in the case of silverblue) knows that you have the exact same comouter as him and if it doesn't work on your pc, it doesn't work on his, because it is the same. Hence, better support for you.

There are cases when different hardware will have different results, even if the OS is 1:1.

Just wanted to make that part clear too.

image for every DE/wm

Coming from traditional distro (Arch to be specific) I just install it without DE or uninstall the existing one and install the other. Graphical environments are just programs just like any other.
So those images are just a convenience thing? Like Fedora has spins that preinstall desktops to have them out-of-the-box?
How those distro are displayed in (neo)fetch like programs, are they just Fedora or their own thing?

Graphical environments are just programs just like any other.

They are in Fedora, too. It’s just that installing one DE overtop another can cause config file clashes (ie installing Plasma alongside GNOME means GTK apps will have a minimize button when logged into GNOME)
