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.

Updates can't really break anything, and if something would go wrong, I can simply boot on the previous image, which will still be there. They can also happen in the background, such that I don't even know it's updating. It just happens and never bothers me.
What's even more interesting is that you can rebase on another base image without having to worry. If I don't like it, I can just go back to the previous image. With ublue, you can even customize your own OS image.
I believe modern Android uses a similar concept. They use two partitions, and install an update to the other image while your phone is running normally. Then all you need to do is reboot, and you'll be on the new boot image.
I believe the Steam Deck also uses a similar concept too. It's very valuable for a company to deliver system updates to appliance-type devices without the risk of breaking anything
Oh, ok. Thank you !
