I assume you mean 'uname -n', since the processor probably isn't interesting.

I would agree with that, or with using the gethostbyaddr / getaddrinfo methods
which pass through the local NSS stack. Those later are the functions that
the majority of Unix daemons (Apache, Postfix, sendmail, etc) use to determine
the FQDN automatically.
hostname -f is implemented the same way, and by design uses NSS, which means
that the local sysadmin can configure that to do whatever oddness is required
WRT local files, DNS, LDAP, NIS, WINS, or any other name service.

*nod* Using the recommended method this would require only documenting:
in /etc/hosts edit it to contain:
you.ip.address hostname.local.domain hostname

Generally, the hostname on Linux does not contain dots, as it is supposed to
be only the local node name. (eg: uname -n)
Full name stuff comes out of NSS, as used by hostname, etc, and which for most
people means that you are looking at the NSS files module and /etc/hosts.

I can't actually speak for the *BSD stack, but I understand they are similar.
