How do I freeze the OTA application so I don't have the notification? topic

I'm on rooted 5.0 and got the 5.0.1 OTA notification. I'm planning to run Cyanogen once it becomes official and don't want to bother wiping data, flashing the stock recovery, etc.

What do I freeze in Titanium to stop the update notification? I searched but couldn't find an answer. Thanks in advance!
