Curious about Linux Disk Partitions... Perhaps Ubuntu Server?

If you're curious about the different directories and want to learn more about their purpose, check out this page. Ironically, I have been looking for a page that has this information, and ironically I happened to have stumbled across it tonight without even looking for it. Here's the link: http://linuxcommand.org/lts0040.php
