hostname and hostname --fqdn mystery

I have just installed a fresh Ubuntu 12.04 LTS server named home. Why not. Preparing the installation of PHP with fastcgi and nginx, inspired by this tutorial, I was puzzled by the fact I get home with the commands hostname and hostname -f.

I'm expected to receive the fully qualified domain name when using the hostname -f command.

It takes some time and manual page reading to find out that this result is normal. Indeed the /etc/hostname file must contain the server name, and not the fully qualified domain name.

The right command to use to get the fully qualified domain names is
hostname --all-fqdns and not hostname -f. There is no need to change the /etc/hosts file. It should contain
127.0.0.1       localhost
127.0.1.1       home
This 127.0.1.1 is weird, but it was set so by default.
