We just installed today with the new install scripts on 5.1 before they announced 5.2. I think we will stay with 5.1 for a few weeks to a month, once it runs perfectly on 5.1, cvsup the system to 5.2 and see if it breaks anything.
But if it runs on 5.1 fine, there is no real reason I can see why it won't run on 5.2 fine. I see no changes between the two that would effect DA.
