Use-case: my FreshRSS service would start before my iSCSI drive was mounted, meaning I had to restart the service for it to pick up the configuration files on my iSCSI. Doing this makes the Docker systemd service depend on the specific mount systemd service - it won’t start until after the iSCSI drive is mounted.
