Я пишу службу Systemd (написано в соответствии с указаниями:Как запустить скрипт с помощью systemd прямо перед выключением?) для синхронизации, шифрования и отправки некоторых файлов при каждой перезагрузке или выключении. Запуск скрипта вручную работает безупречно, но если разрешить Systemd запустить его, возникает несколько проблем:
- Кажется, скрипт запускается не по порядку (
git addпоявляется первым, хотя должен быть последним) - В связи с проблемой, описанной выше, скрипт игнорирует
--git-dirи, по-видимому, пытается добавить всю файловую систему в репозиторий git.
