Я действую согласно инструкции https://www.linode.com/docs/guides/start-service-at-boot/.
Что делаю: создал в корне домашней директории два файла test_service.sh и myservice.service с таким содержанием:
test_service.sh:
DATE=`date '+%Y-%m-%d %H:%M:%S'`
echo "Example service started at ${DATE}" | systemd-cat -p info
while :
do
echo "Looping...";
sleep 30;
done
myservice.service:
[Unit]
Description=My Shell Script (VentoyWeb 1.0.71)
After=network.target
[Service]
cd /home/dragonserw/Public/ventoy-1.0.71/
ExecStart=/home/dragonserw/Public/ventoy-1.0.71/VentoyWeb.sh -H 192.168.88.48
[Install]
WantedBy=multi-user.target
Затем я в домашней директории применяю две вот такие команды:
sudo cp test_service.sh /usr/bin/test_service.sh && sudo chmod +x /usr/bin/test_service.sh
sudo cp myservice.service /etc/systemd/system/myservice.service && sudo chmod 644 /etc/systemd/system/myservice.service && sudo systemctl enable myservice
После этого перезагружаюсь, и статус у сервиса такой:
dragonserw@raspberrypi:~ $ sudo systemctl status myservice

Что удивительно, команда
sudo systemctl restart myservice && sudo systemctl status myservice
оживляет сервис!
