Is the OS X Lion clean installation less stable than the upgrade install? I upgraded to OS X Lion yesterday, everything went fine and I used it for the day without crashes or problems. In the evening, I decided to burn myself a DVD from the installer, and I did a clean install. Am I the only one to notice that the OS X Lion clean install is buggier than the upgrade? Why is that?

Examples of "buggier":


I wasn't able to finish the initial user account set up. At the moment of taking a picture of myself for my account, I got away from my computer 10 minutes, it seemed to go on sleep, and it never woke up. 
After that, on the login screen, I entered my pwd, pressed ok, and the wait cursor showed up. I let it spin for 10 minutes, then got tired of it and restarted the computer.
Finally, this morning, after my computer woke from sleep mode, the mail full screen application froze on an administrator login screen.


--EDIT--

After a couple of weeks of using Lion, everything goes smoothly. The issues I had have gone away automatically.
The DVD install is not an official, sanctioned by Apple, way to install the OS. So it's not that surprising that thing don't go as smoothly.  

Or maybe it's just bad luck when burning or installing the OS. So you can try to install it once again, even burning another DVD to see if that was the problem.

If you want to do a clean install, there will be official USB key in August. But they'll cost more that two times the price of Lion on the Mac App Store
