我嘗試修改此腳本以使用以下庫啟動 Motion。
我透過在終端機中輸入以下命令來啟動腳本：
sudo /etc/init.d/motion start
這使：
start-stop-daemon: user '/etc/motion/motion.conf' not found
Starting motion detection daemon: motion failed!
我已經三次檢查了motion.conf 檔案是否具有正確的權限並且位於/etc/motion/ 目錄中。
如果我在終端機中輸入以下命令，Motion 會正確啟動。
LD_PRELOAD=/usr/lib/uv4l/uv4lext/armv6l/libuv4lext.so motion -c /etc/motion/motion.conf
劇本已經進入/etc/init.d並被稱為“動作”。
#!/bin/sh -e

在 Anthon 和 Mikeserv 的幫助下，以下是更多資訊：
1）命令：ls -lrt /var/log
給出：
-rw-r----- 1 root adm 122336 十月 12 日 08:10 auth.log
2) auth.log 條目給出：
08:10:26 raspberrypi sudo：pam_unix（sudo：session）：使用者 root 的會話已關閉
答案1
將這些行替換 LOAD_LIBRARIES.... 為：
export LD_PRELOAD=/usr/lib/uv4l/uv4lext/armv6l/libuv4lext.so
這使得 LD_PRELOAD 設定可用於從腳本呼叫的命令/程式（例如motion
還有那條線if start-stop-daemon --start ....
if start-stop-daemon --start --oknodo --exec $DAEMON -b --chuid motion $DAEMON -c /etc/motion/motion.conf ; then
該start-stop-daemon選項--chuid將使用者名稱作為參數，因此我希望motion是該名稱。這在原始行上沒有留下任何命令，這就是為什麼您應該在motion其中插入 $DAEMON （ 的完整路徑）及其命令列參數。

經過幾個小時的挫折和論壇成員的大量幫助後，我終於讓它工作了。我絕不是透過發布答案來獲得此榮譽，並感謝人們給我的所有幫助；但為了完整起見，我就是這樣做的。
export LD_PRELOAD=/usr/lib/uv4l/uv4lext/armv6l/libuv4lext.so我在腳本中添加了該行/etc/init.d/motion，並確保我保存圖片的資料夾具有權限，以便用戶動作可以寫入它 -opps！
