I was trying to setup lm-sensors (Community Guide) and when I get to step 4 (sudo service module-init-tools restart) the service fails to start.



In /var/log/upstart/module-init-tools.log I get an entry: "FATAL: Module rtc not found."



Here's my /etc/modules:



# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

loop
lp
rtc
# Generated by sensors-detect on Wed Jul 31 15:15:33 2013
# Chip drivers
coretemp
w83627ehf


So my question is, 1) How are those first few modules determined and is rtc there by mistake? and 2) Can I safely remove rtc from the list since it's not being found anyways?

The tool that loads modules in kernel is 'modprobe'.



From its manpage,




'modprobe' looks in the module directory /lib/modules/$(uname -r) for
all modules and other files, and also the optional configuration files
in the '/etc/modprobe.d'. 'modprobe' also find modules kernel from command
line, in the form of module.option and blacklists in the form of
modprobe.blacklist=module.




For a detailed description of what 'rtc' does, the link is this one. This is not strictly needed to the system, but only to some app. Perhaps your system does not have such app and it is safe to remove.
