I guess my understanding of the host file is clouded the host-file is simply the same as DNS in both directions and does nothing than resolve name/ip locally, normally not needed but maybe a good idea to make sure servers like httpd starts even if no dns is reachable at this moment because httpd refuses to start if he can not resolve his own name
