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.

Hey! I’m currently on Fedora Workstation and I’m getting bored. Nothing in particular. I’ve heard about immutable distros and I’m thinking about Fedora Kinoite. The idea is interesting but idk if it’s worth it. CPU and GPU are AMD. Mostly used for gaming.

The immutable part (again, only speaking about Silverblue, I don't know about others) refers to the inability to make changes online (i.e. without rebooting), but you can eventually change whatever file you want. The way it works is you would make your changes in a copy of the current filesystem and at boot simply mount and use the copy. If something goes wrong, you just mount the original at next boot and you have rolled back.

Fantastic. Thanks for explaining that to me. That actually sounds very good and not at all restrictive. Cool. I can see why things are moving in that direction.

If you do a rollback, I assume your data remains? I assume you might need to reinstall apps which were not in the original? Or does it keep apps, data and settings across a restore?

In CoreOS (Silverblue), /etc, /var and /home (which is in fact a symlink towards /var/home) are regular writable partitions, so your data, configs and personal files are not touched by the upgrade/rollback procedure.

All the packages (and their dependencies) you've installed extra are also upgraded/rolledback when you do a system upgrade.

Fantastic. That's cool. Thank you 🙏
