Because:
1. the old version may appear to be working good at the moment
-AND-
2. some people can admit they are lazy (9.2.2 is what came pre- 
installed on this machine)
-AND-
3. some people already have a lot on their plates (there are only so  
many hours in a day).

;-)

That said, I'm spending some time today fixing issues on my named  
servers anyway and I'm never against a bug fix.

Wow, I glanced over this document when I upgraded on rusty, but  
honestly most of it is over my head (I was glad to be updating rusty  
though!). Looking it over again today, I saw a few race condition  
fixes that completely sold me.

If my named server wasn't behind a firewall or was serving the  
public, I wouldn't have ever set up anything but the latest and  
greatest version. But being this is private and not seen by the  
world, my first goal was to simply get what I already had running. My  
next goal was to bury the old 8.2 version I had on rusty. Today I  
should be able to find enough time to update diags (if not at least  
it's high on my list of things that need to get done:).

Many thanks again Mark!
