By optional I mean, don't have update manager even say they're there unless specified. I don't really mind having all the updates optional, but for new users, a new kernel could create more problems than it solves. One thing I don't like about kernel updates is the fact that it resets the Grub menu.lst. Maybe when you install, you could click like an advanced user option which will give you all the updates, and a new user option that will limit some of the updates.
