When it comes to regular day-today updates, I chose to download all updates in the background, and than I'll manually choose to install it.

Especially now that 11.10 was just released and it will probably take a while to download, can I do the same with the upgrade from 11.04 to 11.10 ? So it will download everything in the background and once it'll finish the download, I will be able to apply the upgrade when I want to ?

Can I download the complete release (as if I'm going to do a fresh install) and use that in some way ?
