[Cooker] What's the best way to install Cooker?

[Raymond S. Swaim]

Is it better to update from LM 7.2 to cooker, or better to do a clean install?

The reason why I ask is that when I tried doing a clean install of cooker a 
couple weeks ago, I found I had not menu items in KDE, Gnome, or any other 
window manager.  Adding all these items manually by hand wasn't very 
appealing to me, so I scrapped it and decided to wait until Cooker "cooked" 
a little more.

Has anyone else had this problem?  Anyone done a clean install recently?
