That's not a daemon process.
isn't. And, when a non-daemon backend process is started in an
interactive terminal, the master mythbackend will ask for permission to
upgrade the database. Had you started it with --daemon or -d,
mythbackend would not have asked for permission to upgrade.
The master backend only defaults to upgrading (without prompting) when
it's not started in an interactive shell.
