Public bug reported:

Binary package hint: network-manager

0.8.1+git.20100810t184654.ab580f4-0ubuntu2.1 breaks my /etc/hosts by
attaching my local host's hostname to localhost

It is my understanding that a machine's local host name should NOT be
associated with the 127.0.0.1 or ::1 IP addresses, but rather some other
address that the machine holds. The 127.0.0.1 / ::1 IP addresses should
be identified as localhost / localhost6.

The recent maverick-proposed network manager has led to my machine's
/etc/hosts being broken by NM, by introducing the short hostname of the
machine as the first entry against 127.0.0.1 and ::1 -

127.0.0.1       altimeter       localhost.localdomain   localhost
::1     altimeter       localhost6.localdomain6 localhost6      ip6-localhost   
ip6-loopback
192.168.2.180   altimeter.mxtelecom.com altimeter


Technical correctness aside, this caused my previously functioning Exim 
installation to start rejecting mail, because its determination of the 
machine's primary_hostname switched from "altimeter.mxtelecom.com" to 
"altimeter".
