Não é possível executar um aplicativo (por exemplo, rclone) com êxito como um serviço

Question

Estou tentando executar o rclone-mount no terminal, ele funciona bem, mas não funciona como um serviço (obviamente eu quero autostart isto assim eu não tenho que digitar mount everytime eu reinicio).

Terminal (funciona bem):

/usr/bin/rclone mount --allow-non-empty box:/mydir /home/user1/mydir/

Como systemd service (não está funcionando). Então, quando eu reinicio meu PC, vejo:

o-pc:~$ sudo systemctl status rclone-mount
[sudo] password for user1: 
● rclone-mount.service - rclone mount service
   Loaded: loaded (/etc/systemd/system/rclone-mount.service; static; vendor pres
   Active: inactive (dead)
