Re: rm -rf /*
someone will still find a way to do it, due to ...
... remote login that terminated without being noticed. Like: you were logged in a remote embedded system that you were setting up, it failed, and you want to start over again. You want to erase everything from the root ... but in the mean time, a colleague called for coffee break, and when you come back, the session has been terminated and the dreaded command is executed locally, not on the remote system.
Has happened, not on the root filesystem but on the users $HOME.
