Monday morning mistake: sudo rm -rf --no-preserve-root /

Well colour me unimpressed. It has had idiot-proofing for ages. There is no defense against an idiot who manually disables all the safeguards - this is very different from a whine of "Noooo saaaafeguaaaaards!" (what do you think that -f does? Hint: the long form is --force)

Also, who accidentally types --no-preserve-root, a 19-character typo in a 30-character command, on top of yet another typo, either of which is idiot-proofed ?

I call an absolute pile of bullshit on that story.
