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.

Honestly it is great, i have run the same install since 2017 without having to reinstall. the filesystem is btrfs, it is configured to take a pre and poat snapshot whenever you enter any of the Yast2 GUI GTK apps for system changes, or use zypper cli etc. You can add remove software or make manual changes and break your system. Reboot, go into advanced option scroll through the time stamped snapshots and select the one you want to boot with. it will be read only, but if it is back to the state you want, drop to command line and issue "sudo snapper rollback" that will set current readonly snapshot as your default writable boot snapshot. you can also manually generate a snapahot at any time using the yast fileaystems. They take up little space or time because it is only saving the delta differeneces.
