It's basically what Thomas has pointed out elsewhere. The contents
files just list the extra files that are in the ISO. The core
differences from one live image to the next are the different desktop
setups, and that's all contained within the squashfs - see the
*.packages files for lists of what's contained in the squashfs on each
image.
I'm actually slightly surprised that the contents files are not even
more close together, but this is just down to dependencies. As part of
the live-wrapper run, we add a list of a few extra packages that might
want to be used for installation, *on top of* the desktop system in
the squashfs. The exact list will be modified by dependencies: in some
cases some of the needed packages will already be covered by what's in
the squashfs.
Does that make sense?
