Thanks for your reply and especially for mentioning the bug report.

How exactly?
As you can see in my example (and in the bugreport):
The "search" block contains only the local domain part by default, but it can be changed to whatever suits your needs. Therefor the module relies on information which might be right but don't have to be.

Sys::Hostname is not an option for me, as I need to know the FQDN and not only the host-part of the hostname. It calls "uname -n" [0], which does not have to know the domain-part.

Here's another example: 
mobile:~# head -n2 /etc/resolv.conf
domain example.org
search intern.example.org example.org
mobile:~# python -c 'import socket; print socket.getfqdn();'
mobile.example.org
mobile:~# hostname -f
mobile.example.org
mobile:~# perl -e 'use Net::Domain qw/ hostfqdn /; print(hostfqdn . "\
+n");'
mobile.intern.example.org
mobile:~# perl -e 'use Sys::Hostname; print(hostname . "\n");'
mobile

Anyways, the bug report completely describes my issue, so maybe things will get fixed soon.
