My own horror story: I mounted an NFS share to &#x2F;tmp while working, and forgot to unmount it later.<p>Think about it.<p>Keep thinking about it.<p>Still keep thinking about it.<p>Still not sure why that&#x27;s dangerous?<p>Give up?<p>tmpwatch removes files from &#x2F;tmp with a modification time over a certain amount of days.<p>I owned up, but a colleague <i>swore</i> he had evidence to prove it wasn&#x27;t me, even though I was sure it was.
