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 that update the kernel in-place, or only fix up kernel modules to continue working after the update?
It moves the old kernel modules to the right location for the old kernel to still find them after you've upgraded. When you restart the system to use the new kernel, the old kernel module symlinks are cleaned up.
From what I understand, live kernel patching is only recommended for critical security fixes to server environments where you can't just boot off every user. https://wiki.archlinux.org/title/Kernel_live_patching
Fair enough, and my bad, I though the original question was about live upgrading the kernel, but looking at the thread again, they were just asking about the system not breaking. Thanks for putting the effort into explaining!
