Fancontrol 手動啟動但服務失敗

當從終端啟動 fancontrol 時，它工作正常

# fancontrol
Loading configuration from /etc/fancontrol ...

Common settings:
  INTERVAL=2

Starting automatic fan control...

但是，當將 fancontrol 作為服務啟動時（啟動時或啟動後），它會失敗。

# service fancontrol start
[ ok ] Starting fan speed regulator: fancontrol.
# service fancontrol status
[FAIL] fancontrol is not running ... failed!

將 fancontrol 作為服務啟動與手動啟動（導致其失敗）之間有什麼區別？

Debian Wheezy Fancontrol 初始化腳本

我覺得自己很傻，應該多調查一下。這是答案，以防萬一我搞砸了或其他人也遇到了同樣的問題。另外，非常感謝@Fiisch 的建議並為我指明了正確的方向。

#service fancontrol start當通過或啟動 fancontrol 時#fancontrol，不會印出 /usr/sbin/fancontrol 的錯誤。由於主機板限制，我的感測器被定義為絕對路徑。所以我跑了/usr/sbin/fancontrol。這會導致錯誤

Configuration is too old, please run pwmconfig again

所以我決定看一下 /usr/sbin/fancontrol 看看為什麼。我在第302-307行找到了原因：

# Check for configuration change
if [ -z "$DEVPATH" -o -z "$DEVNAME" ]
then
    echo "Configuration is too old, please run pwmconfig again" >&2
    exit 1
fi

它只是一個簡單的配置更改檢測器！因為，我已經為我的感測器指定了絕對路徑，這不僅沒有必要，而且實際上導致了錯誤。所以我就把它註解掉了。

## Check for configuration change
#if [ -z "$DEVPATH" -o -z "$DEVNAME" ]
#then
#   echo "Configuration is too old, please run pwmconfig again" >&2
#   exit 1
#fi

就是這樣！ fancontrol 現在工作正常並在啟動時啟動。
