I vaguely thought I posted in this thread back then. Back in 1984/5, I had a directory in my homedir called "etc" for of miscellaneous stuff. One day I thought: that's a bad name, I should remove it. I errantly typed "rm -rf /etc". Thankfully I got a "Permission Denied" error. Except, I then did the obvious override, "sudo rm -rf /etc" (1). This was on a VAX 11/780 with about 50 undergrads doing project work on. The command ran for a while and then I heard moans out in the terminal room, as the system crashed. It took us about 3 hours to restore from backup tape. (1) I used to have to explain what "sudo" was, because this happened before we posted it to USENET, and before it was ubiquitous on systems.
