Package: libnss-myhostname Version: 220-5 Severity: important libnss-myhostname not only resolves the configured hostname to local IP addresses, but also 'gateway' to all the gateways. As the postinst inserts myhostname in /etc/nsswitch.conf ahead of dns, this overrides DNS reverse name lookup for the gateway.
I just discovered this because it broke the SSH remote host filtering on one computer - the computer allowed to connect to it is also the gateway router, but it is now seen as 'gateway' and not the name it has in DNS. The manual page states clearly that this module should be used after dns; please follow this advice and put it last on the hosts line. (This was also mentioned in #756224 but there it is claimed that using myhostname in any position causes breakage. For me that's not the case.)
