Daniel;

I suspect you are asking about how to extract more sets after you have
finished your install.

There is nothing magic about the sets -- they are just compressed tar
files, and thus "extract" is simply the command

    cat tarfile.tar.gz | (cd /; tar --unlink -xzBpf - )

so you can run it at any time.
