transmission-daemon does not exit if configuration directory does not exist or is not accessible

[chris_u]

If the configuration directory does not exist or is not accessible (permissions), the transmission-daemon runs anyway. A default configuration is used that looks like the stock settings.json. The web interface at <host>:9091 can be accessed. I think the daemon should fail and exit if it has no access to the given configuration.

Tried with transmission-daemon versions 2.52, 2.77, r14255 on Linux (Ubuntu, Raspbian).

Example:

$ sudo -u debian-transmission /usr/bin/transmission-daemon -g /var/lib/bogus -f -a '*'

Output:

transmission-daemon runs, webinterface is accessible at <host>:9091.
