The preseed to disable the auto update from Ubuntu repo during ISO installation

Tried to search google and didn't find an easy answer. Therefore I needed to look at the apt-setup source, and figured out these two preseeds:

d-i apt-setup/use_mirror boolean false

d-i apt-setup/services-select-ubuntu multiselect ""

The first entry disables the main/update/multiverse etc. The second entry disables the security.
