Hi Stefano, Starting it as root isn't a problem as long as you allow it to drop privileges to another user. In some cases it may be required for opening privileged network ports for example.
By default mosquitto will try to drop privileges to the "mosquitto" user. This is by design. If you want it to stay running as root you should put "user root" into mosquitto.conf. Specifying the "user" option with no user is invalid and will result in the broker being unable to load the config file, exactly as you have found. Could you address problems like this to the mqtt-users mailing list? It isn't well named, but is for discussion of mosquitto user based issues. The mosquitto-devel mailing list is intended for people developing mosquitto itself.
