Subject: liveinit: correctly create an overlay of all installed content.

The 'setup2hd' script will use this readonly overlay to install to your
harddrive.  However, this readonly overlay still contained the Live
customizations which you do not want copied over to your harddrive.
This update fixes the logical fallacy so that 'setup2hd' works properly now.
