HW42 0d0261d1c1 improve update of /etc/hosts
* use 127.0.1.1 under debian (since it's the default there)
 * also set the IPv6 loopback address (::1) since some tools tries to
   AAAA resolve the hostname (for example sendmail)
 * ensure proper /etc/hosts format through postinst-script (hostname as
   last entry)
