||unity-dev|| Where are persistent room attributes stored?

Hi,

I am wondering if persistent room attributes are stored on the database 
anywhere - I can't seem to find them anywhere from phpmyadmin. I can 
only really see them from uAdmin. Does that mean that persistent room 
attributes only persist for rooms that are set not to dieOnEmpty? I have 
been trying to get a persistent room attribute to persist through a 
server restart (as client attributes do) and also in rooms that are set 
to die when empty, but have not been able to do either. Where do the 
persistent room attributes 'live' on the db/server?

Thanks.
