Yes, I understand, but I only work with Gentoo and set it up myself,
instead of depending on a distribution. Also I have a full bind/named
dns running I keep up-to-date and /etc/hosts only contains 'localhost'
as backup and the local hostname is set as I have defined it on every
boot. In mythtv I have never set it explicitly so I can't query
config.xml. In bash I always look at the $HOSTNAME variable, which I
guess is what that function queries or at least they come from the
same source. The difference between calling hostname -s or hostname -f
at the prompt. hostname assumes hostname -s

If somehow it fails I can always add the --host argument, but I like
to always set defaults, it's friendlier than an error and ones I learn
more about python I'll add checks on domain part to remove it, if
present. But it should never be in the local hostname. It means the
system is setup incorrectly.
