+### BEGIN INIT INFO
+# Provides:          sensor-setup
+# Required-Start:    power-on
+# Required-Stop:
+# Default-Start:     S
+# Default-Stop:
+# Short-Description: Power on micro-server
+### END INIT INFO
+
+# Eventually, this will be used to configure the various (mostly
+# i2c-based) sensors, once we have a kernel version that supports
+# doing this more dynamically.
+#
+# For now, we're using it to install the lm75 and pmbus module so that it
+# can detect the fourth temperature sensor, which is located
+# on the uServer, which doesn't get power until power-on executes.
+#
+# Similarly, the pmbus sensor seems to have an easier time of
+# detecting the NCP4200 buck converters after poweron.  This has not
+# been carefully explored.
