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.

Never used Flatpak or Snap in nearly 30 years of using Linux. I might one day but not yet.
I don't use Fedora these days but your package manager will probably have some hooks. Add one to update your Flatpaks when it has finished its main job.
I've seen the term "hooks" used all the time and have always wondered what the need for them is. I was a Windows user my entire life since childhood and recently rectified that a couple months ago.
Unlearning the Windows paradigm of operating systems has been annoying. So many functional aspects of my machine abstracted away made me have to create an entirely new scaffold for learning technology...
A hook is a mechanism for adding functionality at a certain point in a program's normal flow. As a simple example, imagine a program that works by doing three things in order. It could have hooks that allow the user to add actions before or after any individual steps. Each possible point in the flow is a separate hook. One way to implement it is with a directory for each hook in the program's configuration directory, where executables can be placed; the hook runs each executable in sorted order.
I didn't look up any of this, so it may not be the best explanation, but I hope it is helpful.
