I'm not quite sure what you mean here. If you mean the system should always use a fixed hostname I disagree; for a lot of environments you want to set the hostname via DHCP. > Accordingly, the canonical host name of the system should never be > 'localhost.localdomain'; accordingly the system hostname should never > resolve to IP address 127.0.0.1 whose canonical host name is and will > remain 'localhost.localdomain'. Again I do not agree. For a standalone workstation with no network connectivity (and perhaps even without any network device) attaching the hostname to 127.0.0.1 should be fine. > The system hostname should resolve either to the primary NIC's static > IP address (if there is one) or to the address returned by DNS (if > this is available) or to 127.0.1.1 (failing both of the above). The concept of 'primary NIC' does not exist. > A1. The installer writes an /etc/nsswitch.conf file that contains: > > hosts: files dns defaults 'defaults' is a highly confusing name > A2.

That might confuse a lot of people.
