FBSD uses the name for network related functions, such as using it in mail
related functions when communicating with foreign mail servers, offering
the name to services your computer offers, and listening on certain
network sockets for connections based on that name.

The correct 'stuff' would first and foremost: be the FQDN of the box, if
it has one, thereafter, it would be whatever name designation you give it
to comply with the other computers on the network. For instance, my domain
is northnetworks.ca, and my IBM thinkpad (which I am typing this on) is
named ptp. This designation has no correspoinding DNS entry in my DNS for
my domain because it is mobile and never is in one spot or on one single
network, but when I send myself an email from this box to my real email
account, I will be reminded that it came from
'steve at ptp.northnetworks.ca'.
Many services rely on the hostname, regardless of what it is. I notice
when I need a gui app, I #startx, and it tells me that the display name
relates to my pc name. Beyond this, I don't know what else to tell you,
perhaps someone else on the list will have a more detailed analysis on
what the name is used for.

Considering as far as Free is concerned, there is no right answer. The
filling of these fields resides within the information that your computer
or network admin has given you.

I think this answer has already been provided.
Perhaps you may consider contributing your definition above to the
documentation team for inclusion if you wish to see it in future releases
ps. The tld does NOT have to be a standard tld if used on a private net.
