I'm interested in burning a Knoppix live CD to use for one or two programs (for now). Because I will probably want to get more programs later, however, I want to have some room left on the CD after initially putting Knoppix on it. This means that I do not want to download and burn all the software that currently comes on the iso image. Along those lines, I have two questions:

1. Is what I want to do possible?
2. If it is, what are the essential packages that I should look into downloading in order to get Knoppix to work correctly?

More information: My current OS is Windows XP with the NTFS file system. I don't want to install Knoppix on the HD; I want to run it off of the CD.

Thanks for any help.
