I'm thinking that the Fedora init script should be fixed to set a proper
HOME environment variable, i.e.:

HOME=$MYTHTV_HOME
export HOME

Or, assuming daemon supports it, through some command-line option, at least.

After all, a /lot/ of pieces of Myth are built around the concept of
"user's home directory = $HOME".

What benefit does MYTHTV_HOME provide, anyway?
