Reminds me of that day...
I had an interesting experience deleting old user accounts some 30+ years ago as root (the only choice for the system).
For convenience I was using a system provided script that also removed the home directory for a deleted user at the same time.
Everything was going well until I hit that one user who had his home directory set to "/". I have no idea why a regular joe would have his home set that way, but the consequence was that the OS happily ran "rm -rf /" for as long as it could.
Fortunately the system was being repurposed and only required an OS reinstall from -- gasp -- floppies. I forget how many there were, but it was quite a massive pile.
Biting the hand that feeds IT
