      1. BEGIN INIT INFO
  2. Provides: tp-fancontrol
  3. Required-Start: -
  4. Required-Stop: -
  5. Default-Start: 2 3 4 5
  6. Default-Stop: 0 1 6
  7. Short-Description: Starts the tp-fancontrol script as a daemon
  8. Description: This init script starts the tp-fancontrol script as
  9. a daemon to control the fan speed of an IBM
  10. Thinkpad. You have to modprobe "ibm_acpi" for work
  11. with Kernels newer or equel then 2.6.19 or
  12. modprobed it with "experimental=1"
      1. END INIT INFO
  1. Author: Simon Effenberg <savar@schuldeigen.de>
  2. This init script is based on the script by
  3. Ronald Aigner <ra3@os.inf.tu-dresden.de>
  4. Do NOT "set -e"
  1. PATH should only include /usr/* if it runs after the mountnfs.sh script

PATH=/sbin:/usr/sbin:/bin:/usr/bin DESC="Thinkpad Fan Control" NAME=tp-fancontrol DAEMON=/usr/bin/$NAME DAEMON_ARGS="-d" PIDFILE=/var/run/$NAME.pid SCRIPTNAME=/etc/init.d/$NAME

  1. Exit if the package is not installed

[ -x "$DAEMON" ] || exit 0

  1. Read configuration variable file if it is present

[ -r /etc/${NAME}.conf ] && . /etc/${NAME}.conf

  1. Load the VERBOSE setting and other rcS variables

. /lib/init/vars.sh

  1. Define LSB log_* functions.
  2. Depend on lsb-base (>= 3.0-6) to ensure that this file is present.

. /lib/lsb/init-functions

  1. Function that starts the daemon/service

do_start() {

       # Return
       #   0 if daemon has been started
       #   1 if daemon was already running
       #   2 if daemon could not be started
       start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \
               || return 1
       # building DAEMON_ARGS
       [ ${LOG_SYSLOG:-1} = "1" ] && DAEMON_ARGS="${DAEMON_ARGS} -l"
       [ ${QUIET:-1} = "1" ] && DAEMON_ARGS="${DAEMON_ARGS} -q"
       [ ${TEMP_SHIFT:-0} != "0" ] && DAEMON_ARGS="${DAEMON_ARGS} -s ${TEMP_SHIFT}"
       start-stop-daemon --start --quiet --nicelevel -10 --pidfile $PIDFILE --exec $DAEMON -- \
               $DAEMON_ARGS \
               || return 2

}

  1. Function that stops the daemon/service

do_stop() {

       # Return
       #   0 if daemon has been stopped
       #   1 if daemon was already stopped
       #   2 if daemon could not be stopped
       #   other if a failure occurred
       start-stop-daemon --stop --quiet --retry=TERM/30/KILL/5 --pidfile $PIDFILE --name $NAME
       RETVAL="$?"
       [ "$RETVAL" = 2 ] && return 2
       # Wait for children to finish too if this is a daemon that forks
       # and if the daemon is only ever run from this initscript.
       # If the above conditions are not satisfied then add some other code
       # that waits for the process to drop all resources that could be
       # needed by services started subsequently.  A last resort is to
       # sleep for some time.
       start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON
       [ "$?" = 2 ] && return 2
       # Many daemons don't delete their pidfiles when they exit.
       rm -f $PIDFILE
       return "$RETVAL"

}

  1. Function that stop/sart the daemon/service

do_reload() {

       do_stop
       do_start
       return 0

}
