Description: Test for BZ#1580492 (hostname -A failed to parse long hostnames)
Author: Ondrej Mejzlik <omejzlik@redhat.com>
Bug summary: hostname -A failed to parse long hostnames
Bugzilla link: https://bugzilla.redhat.com/show_bug.cgi?id=1580492

The test tries to set various hostnames beginning with one character long hostname.
Up to the maximum allowed 64 chars long hostname. And including a 65 chars hostname testing that
hostname command forbids that.
Hostname -A should display hostnames up to the maximum allowed lenght. Because of the bug names longer 
than 45 chars did not work.
Hostname -A uses DNS to resolve hostname, so /etc/resolv.conf must be empty in order to be able to set
hostname manually and have it affect the hostname -A command.
