Gnoppix is based on Ubuntu, not vice versa (page 564)

In chapter A. Debian flavours and other Debian-based operating systems on page 564:
The last sentence of A.2.3 states that Gnoppix is the basis for the Ubuntu Live CD. This is not accurate. Andreas Müller, the developer of Gnoppix, actually developed the Ubuntu Live CD first, and then reused this work for Gnoppix. Thus, Gnoppix is based on the Ubuntu Live CD, not vice versa.
