Odds and Ends: iTunes 3.0.1 Library Duplication

iTunes 3.0.1 Library Duplication Ben Rosenthal reports a minor library location quirk after updating to iTunes 3.0.1:

"After I installed 3.0.1 (which claimed it needed 328 MB free disk space to install), my Library disappeared. It turned out I had my iTunes 3 Music Library file in ~/Documents/iTunes and iTunes 3.0.1 created a new one in an iTunes folder in the folder containing my music. When I removed the new file (which I discovered by its modification date), and put the older one in its place, all was back to normal."
