So you use your restore disk to:You restore using the restore disk that came with the computer and then you add the upgrades.
It would be nice if they sold a disk but there is no MUST in this game.
- install 10.6.something
- Then you run through the updates to 10.6.latest (so the OS knows about the App Store stuff - because the person needs it for the next step)
- Then you get the Lion installer back on your computer (most users will wind up downloading it again because they never made a DVD backup)
- Then you upgrade to Lion
This sounds painfully long and not a clean user experience. Right now if the person has a time machine backup, they could just install Lion and then have Time Machine get everything else back in place.
And if you use other methods to back up your computer, you're probably the type that would want to do a clean Lion install and then do clean installations of all the applications you use.
