Сценарий автозапуска (Systemd) вылетает

Question

Я хочу автоматически запустить мой скрипт с помощью systemd, который выполняет git checkout, git pull (я уверен, что конфликт не возникнет), а после этого запускает программу на python.Я создал пример, который показывает мою задачу.Но периодически вылетает.Правильно ли установить «TimeoutStartSec = infinity»?Возможно, я должен сделать это по-другому?

TEST_DAEMON.py

#!/usr/bin/python3.7
while True:
    pass

TEST_DAEMON.sh

#!/bin/sh
cd /home/user/TEST_DAEMON/
git checkout master
git pull
/home/user/TEST_DAEMON/TEST_DAEMON.py

TEST_DAEMON.service
