>From the above URL: From: Christoph Anton Mitterer <cales...@scientia.net> Date: Tue, 30 Jul 2013 22:43:44 +0200 ----- - The system hostname (and domainname if any) should ALWAYS be resolvable, whether a network is up or not, regardless of which. (Assuming that lo is always up, if not, many things break anyway.) - "localhost" when added like this to /etc/hosts is basically like a TLD. "localhost" is one of the reserved names, unlike ip6-localhost and friends and unlike .localdomain. ... ... ... Further, but this isn't the case anymore anyway,... we should not generate localhost.localdomain. ... ... ... ----- If system hostname should ALWAYS be resolvable, whether there is network or no, the change in /etc/hosts from (default in stretch): 127.0.0.1 localhost to (my system): 127.0.0.1 localhost localhost.localdomain is justifiable as it breaks (not literally break, just adds lot of delay) to sudo in a non-networked environment. x9p
