I have set up my raspberry pi running ubuntu 20.04 server so it can run teamspeak with box86.
To do that I set up a chroot in ls /srv/chroot/focal-armhf/ with debootstrap. In that directory I compiled box86. I then downloaded and installed ts3server for x86 on linux. I have set up a custom config for schroot.
/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
When I run the following commands in bash on the host, everything works fine.
# 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
I wanted to do this automatically with systemd now. So I created this unit configuration
[Unit]
Description=Teamspeak3 Server in chroot
After=network.target
After=syslog.target
[Service]
ExecStartPre=/usr/bin/schroot -n ts3server -b -c chroot:focal-armhf

ExecStopPost=/usr/bin/schroot -e --chroot ts3server
Restart=no
Type=simple
[Install]
WantedBy=multi-user.target
When I run it however it shuts down immediately after. The teamspeak server log runs is

If I set restart always, it will keep generating that same log over and over again.
It seems like the server is started, then forks to the background, then ExecStop is called by systemd.
I have tried setting Type=forking and Type=exec and Type=simple, all with the same results.
Basically everything works fine, until I try to use systemd to manage it all.
How can I make it work?
In particular I want:
- Automatically start it with the system
- Manage it with
service ts3server start|stop|restart
For completeness sake my custom script to manage teamspeak server:
