Fancontrol 手动启动但服务失败

当从终端启动 fancontrol 时，它工作正常

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

Common settings:
  INTERVAL=2

但是，当启动 fancontrol 作为服务时（在启动时或启动后），它会失败。

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

将 fancontrol 作为服务启动与手动启动有何区别？手动启动会导致其失败吗？

Debian Wheezy Fancontrol 启动脚本

我觉得自己很傻，应该多调查一下。以下是答案，以防我搞砸了或者其他人遇到同样的问题。此外，非常感谢@Fiisch 的建议和为我指明正确的方向。

#service fancontrol start通过或启动 fancontrol 时#fancontrol，不会打印 /usr/sbin/fancontrol 的错误。由于主板限制，我的传感器被定义为绝对路径。所以我运行了 /usr/sbin/fancontrol。这会导致错误

Configuration is too old, please run pwmconfig again

所以我决定查看 /usr/sbin/fancontrol 以找出原因。我在 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

这只是一个简单的配置更改检测器！因为我已经为传感器指定了绝对路径，这不仅没有必要，而且实际上还会导致错误。所以我只是把它注释掉了。

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

就是这样！fancontrol 现在运行正常，并在启动时启动。
