That's the case where the hostname is an alias of localhost.

If you install "libnss-myhostname", you can simply have "127.0.0.1
localhost" in "/etc/hosts" (as well as the loopback ipv6 stuff) and
not have to worry about that file on any box that you manage. IIRC, if
you're using dhcp, it maps the hostname to 127.0.0.2 (which is the old
Debian/Ubuntu hostname ip address).
