[arch-dev-public] Adding nss-myhostname to the base group

Hi guys, I'd like to suggest that we add nss-myhostname to the base group, enable it by default in /etc/nsswitch.conf and make 'filesystem' depend on it. This means that the admin no longer has to make sure that /etc/hostname and /etc/hosts are kept in sync, as nss-myhostname will make sure that the local hostname can always be resolved. In particular this means that most people can leave /etc/hosts unchanged so it should simplify the configuration of a basic Arch system. For more information see: <http://0pointer.de/lennart/projects/nss-myhostname/>. Cheers, Tom
