I download the dvd iso to my HD, and burn cd iso to cd. I boot from cd with the bootfrom parameter. That way my systsem is secure that the dvd image provides, I can boot fast because it boots from the hard drive, and my cd/dvd drive is free for other use. Now if I could install a bootloader that would allow me to boot from the iso instead of the CD I would be all set. All my configuration is also saved to an image on my local drive.

What additional benefits would I get from an HD install. I have installed debian, but that install is not as polished as the knoppix. Then I also have to update the software regularily. With the iso, I am free from that. I just download and install new versions as they come out.
