The fully qualified domain name (FQDN) of this host. It is the result
of combining `networking.hostName` and `networking.domain.` Using this
option will result in an evaluation error if the hostname is empty or
no domain is specified.
Modules that accept a mere `networking.hostName` but prefer a fully qualified
domain name may use `networking.fqdnOrHostName` instead.

Either the fully qualified domain name (FQDN), or just the host name if
it does not exists.
This is a convenience option for modules to read instead of `fqdn` when
a mere `hostName` is also an acceptable value; this option does not
throw an error when `domain` is unset.
