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.

Does a debian version upgrade require an OS reinstall?
For me, no....
I've gone from debian 9 to debian 11 and now debian sid without reinstalling OS on my desktop
Same with my servers. Debian 8 -> 11 all upgrades in-place. Will have to upgrade to 12 soon....
The only time i messed up an upgrade is when accidentally used the codename "bookworm" in the sources file and skipped a major version. The system tried to fully upgrade 2 versions ahead and promptly borked itself.... But it was an LXC container so i just rolled back my mistake. Lesson learned...
But yeah. Full re-installs have NEVER been a thing for me since going debian. It will even happily clone to a new SSD when you need to upgrade your hardware. (As long as your new hardware has in-kernel drivers, or at least some basic functionality to boot and fix the problem, if any)
