It's dated a couple days ago, so I'd say it's doing what it's supposed to.  I'm 
not sure what the "dbus" notification does, but I presume it's telling someone 
to do the updating.  It'd probably be more informative if I could understand who 
is picking up such notifications.

Do you know how to determine which repo a particular package is from?  For 
example, when I do "yum info" against clamav (which isn't receiving automatic 
updates), it just says "Repo: installed".  I don't know what repo it comes from.

Thanks much
