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.

Pro tip there!
Thankfully, it appears this is no longer necessary in most cases since 2022: https://wiki.archlinux.org/title/Pacman/Package_signing#Upgrade_system_regularly
Though, it's still worthwhile doing it for computers you don't power on for most of the year, as the service likely hasn't had a chance to run.
