     Thanks for this, and the other, clarifications. I'm still trying to 
understand just what's going on. Let me see if I can recap this.
1) The local system needs to know both its hostname and its domain (both of 
which compose the fully-qualified domain name).
2) The /etc/hosts file needs to contain the local system's name in its 
fully-qualified form (I haven't tried this with ONLY the fully-qualified 
name: I've only done the opposite).
3) The hostname portion may be changed via the hostname command but that 
change is lost when the system is rebooted.

And 4) [and this is where things get a little mushy in my mind], 
".localdomain" is automatically supplied as the domain name when it is 
otherwise missing, and should, therefore, be added (by hand) to /etc/hosts in 
those situations.
     How's that?
     A related question is where *should* the domain name be defined? I've 
been told by others that it should *not* appear in the HOSTNAME=xxxxx line in 
/etc/sysconfig/network but I don't know why.
