on centos, chef returns the same hostname and fqdn as the responses from the hostname and hostname -f commands

On an Ubuntu box, let's say the hostname is machine1.example.com.

In /etc/hosts, the first line is

What will chef consider the fqdn and hostname?    Apparently just "machine1".

Now that I have discovered this strange quirk, I wonder if I should use this on
purpose, to make the machine names smaller.     Or, be careful to avoid this
loophole.    I am just thinking out loud.    Do people generally use the whole
fqdn...

when you're doing a reverse lookup on 1.2.3.4 with that config you're getting back the first name which is the short hostname.  to get the FQDN just reverse that to:

1.2.3.4 machine1.example.com machine1
