我制作了一个 LSBized 初始化脚本，它在启动时运行一些脚本，然后在脚本被杀死或关闭时重新启动它。

起初一切看起来都很好，但几分钟后 init 脚本停止，另一个脚本继续运行。

我在 /var/log/syslog 中收到此错误

Jun  9 14:53:49 debian systemd[1]: test.service start operation timed out. Terminating.
Jun  9 14:53:49 debian systemd[1]: Failed to start LSB: Start some script on boot and restarts it if it stops..
Jun  9 14:53:49 debian systemd[1]: Unit test.service entered failed state.

我的脚本如下所示：

#! /bin/sh
# /etc/init.d/test
#

### BEGIN INIT INFO
# Provides:          $parentscript
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start some script on boot and restarts it if it stops.
# Description:       Start some script on boot and restarts it if it stops.
### END INIT INFO

start() {
until /home/user/runthis; do
    echo "Process crashed with exit code $?.  Respawning.." >&2
    sleep 1
done

}


# Carry out specific functions when asked to by the system
case "$1" in
  start)
        start
        ;;
  stop)
        echo "Stopping script test"            
        ;;
  *)
        echo "Usage: /etc/init.d/test {start|stop}"
        exit 1
        ;;
esac

exit 0

我在 Debian 8.0 x64 和 x86 上试过，这两种情况都会发生同样的事情。

有什么我做错了吗？或者有没有其他方法可以达到同样的效果？谢谢！
