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've had bad tinkering break my system before, but never had an update break it irreversibly. The closest would actually be on Silverblue itself, when an update to the kernel was using different signing keys that cause the system not to boot. Fortunately it was simple, I selected the previous deployment and I was in (on a non versioned OS I would have selected the previous kernel which most are configured to retain the last few). A quick Google revealed Ublue had a whole kerfuffle and after verifying it was legit, I enrolled the new certs into my MOK.
Although one time on Arch I had installed an experimental version of Gnome from one of their repos, and was pleasantly surprised when that version finally released and I removed the experiment repo and did an update absolutely nothing at all broke. Nothing.
Not irreversibly, but it's annoying to be forced to spend an hour searching for an answer in forums then fixing to get networking or GUI back before you can do productive work.
