Comment 7 for bug 546616

Even if I'm not affected by this exact bug the lack of proper environment settings (like $HOME) are making my mythfilldatabase fail:

...
2010-04-09 13:16:53.430 Using runtime prefix = /usr
2010-04-09 13:16:53.446 Using configuration directory = /.mythtv
2010-04-09 13:16:53.446 Unable to read configuration file mysql.txt
2010-04-09 13:16:53.446 Empty LocalHostName.
...

I believe this comes from how the mythbackend process is launched in /etc/init/mythtv-backend.conf which executes the process without setting the environment. This said I was able to resolve the problem by launching mythbackend after a switch user to mythtv with "--login" option.

The modified version of /etc/init/mythtv-backend.conf is attached.
