Observe that "hostname" and "dnsdomainname" were the only executables
in the package "hostname" of Debian GNU/Linux until 2009 in version 2.97.
Only then did "domainname", "ypdomainname", and "nisdomainname" enter.

In addition, for GNU/Linux "domainname" is an interface into the settings
of the Linux kernel, it has nothing to do with the resolver. Hence it will
return "(none)" unless the kernel has been told otherwise. This is in
accordance with the mechanisms for BSD systems.
