Now that you have your uncompressed Knoppix live filesystem, the idea behind remastering it is that you have this filesystem in a read-write environment (as opposed to the read-only environment of the CDROM). The only problem is that you have to separate yourself from your installed linux environment so that you can operate in the knoppix live environment which resides on the same filesystem. To achieve this, we us a technique called chrooting. To chroot is to lock yourself into an environment based on some place in a filesystem structure. For instance, when you FTP into some server on the internet, you can only move up directories to a certain point in the filesystem. Maybe this point is your home directory. If you try to "cd /" you end up in your home directory (which is not the real root directory of the drive you are on. This is because you have been chrooted to your home directory upon logging in to the FTP server. In effect, the root directory to you is your home directory.

To operate in the Knoppix live filesystem without disrupting our installed linux filesystem, we'll chroot ourselves into the directory we have chosen to remaster in (mine would be /share/knoppix-remaster/source/KNOPPIX.
