Pardon me as I am not sure what you are asking but here goes...When you install Knoppix you can only install it to a single partition. It won't install /home /var etc. seperately. It is possible however to install Knoppix and then move your directories to their appropriate partitions. Stephen has posted a very excellent how-to on that very subject should you care to read it.

I hope this is what you were asking about. If not of course please post back.
