I always wanted the /dev/zero character device driver, which you can map into memory to clear it, or use as an infinite source of nulls, to use the minor node number as the value that got mapped into memory or produced, so you could make an infinite source of beeps with:<p>mknod /dev/seven c 1 7<p>I wonder what would happen if you made a /dev/seven device in your http servers public_html directory? Would it dutifully serve it up?<p>Better yet, support for utf-8 unicode, so you can make an infinite source of poo emojis.<p>The "Everything Is A File" philosophy should be taken to its logical conclusion.
