The glibc documentation blows for this, but what getdomainname comes
from uname(2), not from any DNS-related configuration. Debian only
ever sets this if you're using NIS.
There's no real great way to get the current hostname; a lot of
applications do a reverse DNS lookup on the primary network interface,
with appropriate handwaving to define primary.
Easiest might be to punt to hostname --fqdn, or an equivalent to its
algorithm - which appears to be fetch the hostname from uname, do a DNS
lookup on that, and a reverse DNS lookup on the result.
