CD on Linux

Because something was wrong with the ISO creation on my Windows laptop, I inserted a CD to a Linux box to create an image there. To my surprise, my Linux box auto-mounted the CD and created an icon on the desktop. Since I haven't used CD on Linux for a long time, I didn't know that it became this easy to use CDs. But, for today's purpose, all I needed to do is "dd if=/dev/cdrom of=cd.iso".
