我已经设置了运行 ubuntu 20.04 服务器的 Raspberry Pi，以便它可以与 box86 运行 teamspeak。
为此，我ls /srv/chroot/focal-armhf/使用 debootstrap 设置了一个 chroot。在该目录中，我编译了 box86。然后，我在 linux 上下载并安装了 x86 版 ts3server。我为 schroot 设置了一个自定义配置。
/etc/schroot/chroot.d/focal-armhf.conf：
[focal-armhf]
description=Ubuntu focal armhf chroot
type=directory
directory=/srv/chroot/focal-armhf
profile=ts3server
personality=linux
# preserve-environment=true
root-users=ubuntu
users=ubuntu
当我在主机上的 bash 中运行以下命令时，一切正常。
# beginn session, name it ts3server
sudo /usr/bin/schroot -n ts3server -b -c chroot:focal-armhf
# run start script. it's the same as the default start script, however I added /usr/local/bin/box86 in front of the starting of the actual server binary.
sudo /usr/bin/schroot --run-session --chroot ts3server -d /opt/ts3server/teamspeak3-server_linux_x86/ './ts3custom.sh' start
# at this point the server is running and i can connect to it.
# ...
# when I want to shut down:
# stopping server
/usr/bin/schroot --run-session --chroot ts3server -d /opt/ts3server/teamspeak3-server_linux_x86/ './ts3custom.sh' stop
# ending schroot session
/usr/bin/schroot -e --chroot ts3server
我现在想用 systemd 自动执行此操作。所以我创建了这个单元配置
[Unit]
Description=Teamspeak3 Server in chroot
After=network.target
After=syslog.target
[Service]
ExecStartPre=/usr/bin/schroot -n ts3server -b -c chroot:focal-armhf

Restart=no
Type=simple
[Install]
WantedBy=multi-user.target
但是当我运行它时，它会立即关闭。teamspeak 服务器日志运行是

如果我设置始终重启，它将不断生成相同的日志。
好像服务器启动后，然后分叉到后台，然后 systemd 调用 ExecStop。
我尝试设置Type=forking和Type=exec和Type=simple，结果都相同。
基本上一切都运行良好，直到我尝试使用 systemd 来管理这一切。
我怎样才能让它工作？
我特别想要：
- 随系统自动启动
- 管理它
service ts3server start|stop|restart
为了完整起见，我使用自定义脚本来管理 Teamspeak 服务器：

我在使用 tmux 时遇到过类似的问题，解决方法如下：
[Install]
WantedBy=multi-user.target
[Service]
Type=oneshot
RemainAfterExit=yes
KillMode=none
User=root
ExecStart=...
WorkingDirectory=
看起来该服务已结束，因为其父服务（服务）已停止。RemainAfterExit 和 KillMode 有所帮助...
