This Linux storage feature feels like cheating once you understand it

Storage is one of those parts of Linux that most people only think about when something breaks. You pick a file system during install, trust it with your files, and then forget it exists. It sits under everything: your OS, your home folder, your logs, your downloads, your work, and all the small mistakes you make while changing things. For years, that mostly means one thing: when a file changes, the old data is overwritten by the new data, and you move on.
