Did you get an answer to this? 

/etc/hosts seems to often have localhost.localdomain in it by default.
I thought this is just for hostnames though?
Perhaps it's only the DNS that knows about domain names?
I'm not sure if having a dial-up connection changes things because your
domain name might change depending on which ISP you dial.

I've noticed that the hostname seems to pick up the first name from the
last line in my /etc/hosts (I've set up several alias hostnames to test
Apache virtual domains). I noticed in /etc/rc.d/rc.sysinit it says:
"HOSTNAME=`/bin/hostname`" but this is a binary so I've not looked in to
how it works.

I think you can do all the hostname/domain name setting in linuxconf but
it is nice to know what files it uses behind the scenes.
