我尝试修改此脚本以使用以下库启动 Motion。
我通过在终端中输入以下命令来启动脚本：
sudo /etc/init.d/motion start
这使：
start-stop-daemon: user '/etc/motion/motion.conf' not found
Starting motion detection daemon: motion failed!
我已经三次检查了motion.conf 文件是否具有正确的权限并且位于/etc/motion/ 目录中。
如果我在终端中输入以下命令，Motion 会正确启动。
LD_PRELOAD=/usr/lib/uv4l/uv4lext/armv6l/libuv4lext.so motion -c /etc/motion/motion.conf
剧本已经进入/etc/init.d并被称为“动作”。

在 Anthon 和 Mikeserv 的帮助下，以下是更多信息：
1）命令：ls -lrt /var/log
给出：
-rw-r----- 1 root adm 122336 十月 12 日 08:10 auth.log
2) auth.log 条目给出：
08:10:26 raspberrypi sudo：pam_unix（sudo：session）：用户 root 的会话已关闭
答案1
将这些行替换 LOAD_LIBRARIES.... 为：
export LD_PRELOAD=/usr/lib/uv4l/uv4lext/armv6l/libuv4lext.so
这使得 LD_PRELOAD 设置可用于从脚本调用的命令/程序（例如motion
还有那条线if start-stop-daemon --start ....
if start-stop-daemon --start --oknodo --exec $DAEMON -b --chuid motion $DAEMON -c /etc/motion/motion.conf ; then
该start-stop-daemon选项--chuid将用户名作为参数，因此我希望motion是该名称。这在原始行上没有留下任何命令，这就是为什么您应该在motion其中插入 $DAEMON （ 的完整路径）及其命令行参数。

经过几个小时的挫折和论坛成员的大量帮助后，我终于让它工作了。我绝不是通过发布答案来获得此荣誉，并感谢人们给我的所有帮助；但为了完整起见，我就是这样做的。
export LD_PRELOAD=/usr/lib/uv4l/uv4lext/armv6l/libuv4lext.so我在脚本中添加了该行/etc/init.d/motion，并确保我保存图片的文件夹具有权限，以便用户动作可以写入它 -opps！
