What rpm does (at least for a few different versions I have handy) is 
call gethostname and then call gethostbyname on the result. If the 
gethostbyname call succeeds, then the name is pulled from that result, 
otherwise it sticks with the first result but logs a "Could not 
canonicalize hostname" warning.

So it's /trying/ to get the fqdn. Are you seeing "Could not canonicalize 
hostname" warnings?
