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

# The format of that file a shell script that simply defines the modules 
# in order as normal shell variables with the special names:
#    MODULE_1, MODULE_2, MODULE_3, etc.

# If sensors isn't supported by the kernel, try loading the module...
[ -e /proc/sys/dev/sensors ] || /sbin/modprobe i2c-proc &>/dev/null

# Don't bother if /proc/sensors still doesn't exist, kernel doesn't have
# support for sensors.
[ -e /proc/sys/dev/sensors ] || exit 0

# If sensors was not already running, unload the module...
[ -e /var/lock/subsys/sensors ] || /sbin/modprobe -r i2c-proc &>/dev/null

# Source function library.
#. /etc/init.d/functions

# Shell functions sourced from /etc/rc.status:
#      rc_check         check and set local and overall rc status
#      rc_status        check and set local and overall rc status
#      rc_status -v     ditto but be verbose in local rc status
#      rc_status -v -r  ditto and clear the local rc status
#      rc_status -s     display "skipped" and exit with status 3
#      rc_status -u     display "unused" and exit with status 3
#      rc_failed        set local and overall rc status to failed
#      rc_failed <num>  set local and overall rc status to <num>
#      rc_reset         clear local rc status (overall remains)
#      rc_exit          exit appropriate to overall rc status
#      rc_active	checks whether a service is activated by symlinks
#      rc_splash arg    sets the boot splash screen to arg (if active)
. /etc/rc.status

# Reset status of this service
rc_reset

# Return values acc. to LSB for all commands but status:
# 0	  - success
# 1       - generic or unspecified error
# 2       - invalid or excess argument(s)
# 3       - unimplemented feature (e.g. "reload")
# 4       - user had insufficient privileges
# 5       - program is not installed
# 6       - program is not configured
# 7       - program is not running
# 8--199  - reserved (8--99 LSB, 100--149 distrib, 150--199 appl)
# 
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signaling is not supported) are
# considered a success.
