I have looked both in the FAQs (which didn't have the information) and the wiki (which had outdated info that didn't help enough) and I still don't really get the differences.
When downloading something with the app loader built in, you can download it as the following:
* OnBoot
* OnDemand
* Download + Load
* Download Only
I understand that "Download only" just downloads the installing file, but the other three is unclear to me. Can you tell me the difference?
