Hello,

in the /etc/init.d/mongod script under Debian is a "CONF" variable which points to the "/etc/mongod.conf" standard config. If you change the path to your own YAML config, so your config is used at every startup, MongoDB is not able to start. It breaks simply with "mongod failed!", no error is logged. This is very annoying because when you want to use wiredTiger it is only possible when you use the YAML format. When you start the database with "mongd --config /path/toyour/YAMLconfig" it runs smoothly but not if you change the CONF variable in the Debian init script. I add my YAML config as Attachment.

Thanks for your attention
