It's a (albeit hacky) way to set up a pseudo-home directory for the
mythbackend daemon when a "normal" $HOME variable is not defined
during init. It should ensure that no /.qt and /.mythtv directories
are created.

It is more elegant to provide it as a user-configurable variable and
then export it. I'm waiting for some feedback from Anduin on a patch I
submitted against the init script that checks for the presence of this
directory due to the way the script had been updated to start the
bakcend from a possibly missing directory, but exporting $HOME would
be the optimal method of sorting out the issue.

I tend to think of mythbackend as a daemon and choose to keep it's
config somewhere under /etc rather than in a "regular user's" /root or
/home directory. I see mythfrontend as a GUI-driven user application,
but there's a need to share configuration information to be able to
access the DB/display icons etc and herein lies the heart of the
issue, as I see it.
