in this first section, we mostly describe the 2 different processes (SD install vs SD boot). At this stage , I don’t think it makes sense to talk about pre-installed packages, because we are not talking about actual images, but just the boot/install process. e.g. there could be many SD install images, or SD boot images.
in the section later with more instructions to use the SD boot image, just before you get to downloads, we have a note that says:
Note that this installation option only installs a “developer image,” i.e. command line only with no desktop installed. A user would have to install a desktop post-install if that is desired.
Do you still think we need more clarification?
