我有两个覆盆子。旧的运行 Raspbian/Debin 4.9.35+，新的运行 5.15.32。在旧版本上，我的 daemontools 可以顺利工作，并且在重新启动后也可以顺利启动 MyService：
$ systemctl status daemontools.service
● daemontools.service - Daemontools service supervision
Loaded: loaded (/lib/systemd/system/daemontools.service; enabled)
Active: active (running) since Sa 2022-07-30 19:23:19 CEST; 21h ago
Main PID: 368 (svscanboot)
CGroup: /system.slice/daemontools.service
├─368 /bin/sh /usr/bin/svscanboot /etc/service/
├─379 svscan /etc/service
├─380 readproctitle service errors: .... "Morgens"=830 und "abends"=2127 31.07. 16:23:56 INFO - [eg-...
├─384 supervise myProg
└─386 java -Duser.timezone=Europe/Berlin -Dfile.encoding=UTF-8 -jar myProg....
在新机器上，我使用 agt-get 安装了 daemontools，但之后没有任何运行或准备。所以我将 /lib/systemd/system/daemontools.service 从旧的 Pi 复制到了新的 Pi。
[Unit]
Description=Daemontools service supervision
[Service]
ExecStart=/usr/bin/svscanboot /etc/service/
Restart=always
[Install]
WantedBy=multi-user.target
然后我“启用”该服务并启动它并收到错误：
pi@jc04:~ $ systemctl status daemontools.service
● daemontools.service - Daemontools service supervision

使用journalctl会带来以下结果：
journalctl -u daemontools.service

在我看来，好像 daemontools 启动并立即完成，持续了 5 次，然后 initd 打破了循环。为什么新发动机会出现这种情况，为什么同样的结构在旧发动机上却有魅力？ PS：daemon-reload和egine重启没有改变任何东西。
问候并谢谢您！
