fancontrol init script for ubuntu +

[catkin]

Hello :-)

Here's a standards-compliant init script for fancontrol, developed and tested using fancontrol 0.66 on ubuntu 8.04.1. It may work on other ubuntus, debian and other debian-based systems using lsb-base (>= 3.0-6).

Part of the standards-compliance is that the script issues no messages at boot or shutdown if /etc/default/rcS has VERBOSE=no (the default value)

The init script can be installed issuing the following command (with root privileges)

update-rc.d fancontrol defaults 99 01

BTW, pwmconfig from the current ubuntu lm-sensors package (1:3.0.0-4ubuntu2) does not set START and STOP values; use the version from the 3.0.3 package.
