While setting up lm-sensors and fanconrtol packages on Ubuntu 13.04, I arrived at a stage were I had to restart the service modules-init-tools to apply changes to the /etc/modules file then alas! I got "modules-init-tools: unrecognized service". I know a reboot of the system will most likely apply the changes. But I want to know where the service is or if it has been replaced how do I restart it from terminal without doing a reboot.
