# It uses a config file /etc/sysconfig/lm_sensors that contains the modules
# to be loaded/unloaded. That file is sourced into this one.

# The format of this file is a shell script that simply defines variables:
# HWMON_MODULES for hardware monitoring driver modules, and optionally
# BUS_MODULES for any required bus driver module (for example for I2C or SPI).

# Do not load RH compatibility interface.
