This principal (and the general UNIX tradition of putting the local host
and IP address in /etc/hosts) has caused us no end of problems, since that
information inevitably gets out of date when systems are moved around or
re-IP'd. We now do not put the local hostname anywhere in /etc/hosts, and
I believe that's the correct configuration for any system with stable DNS
and network.
