What happens if Linux deletes / #linux

Key Takeaways

Linux slash the root directory. The beginning, the end, the place where everything lives. This is Linux slash in 100 seconds. Linux is built on a simple idea. Everything is a file. Your binaries, your configs, your users, your logs, your device drivers, your soul. All of it lives under one directory. The root directory written as a single forward slash slash. Now, what happens if Linux deletes slash? First, modern Linux tries to save you from yourself. If you run rm-rf/ you'll usually get an error, something like it is dangerous to operate recursively on slash. Linux is basically saying, "Hey buddy, maybe don't." But Linux also believes in freedom and poor life choices. So, if you really insist, you can add no preserve route. This flag tells Linux, "Yes, I know what I'm doing," which you don't. The moment this command runs, Linux doesn't explode. It doesn't panic. It doesn't shut down. It calmly starts deleting. First, system binaries vanish. BIN, SBIN, USR, BIN. Commands like LS, CD, RM disappear while they're still running. You can literally delete RM using RM. Next, configuration files are wiped, etc. is gone. Networking breaks, authentication breaks, services stop restarting, then user data starts dying. Home documents, SSH keys, browser profiles, gone. logs disappear, so you won't even know how bad things really are. Processes already running keep running because they're already in memory. This creates a cursed state where the system is alive, but you can't control it. You can't log in. You can't run commands. You can't shut it down cleanly. Eventually, something tries to access a file that no longer exists and the system collapses like a tower of Jenga played by a sleep-d deprived CISADmin. The only real fix is reinstalling the OS or restoring from backups. You do have backups, right? This is why Linux treats slash with extreme respect and why rm-rf slash is the closest thing to a digital self-destruct button. This has been what happens if Linux deletes slash in 100 seconds.
