I'm sure that they have their reasons.  But, I don't think that its 
required in /etc/hosts...  Just reversible [that is, they can look up an 
IP address for your hostname].

In my /etc/sysconfig/network file, I have the following:

NETWORKING=yes
HOSTNAME=localhost.localdomain

Then, my /etc/hosts file has:

127.0.0.1   localhost.localdomain localhost

It works for me with DHCP.

Hope this helps....
