Configure the bcache.ko module to be automatically loaded upon system boot.

View the user and user group of the /dev/acache device.
```
ll /dev/acache
```
Modify the acache_client.service file. Set the user and user group to the current owning user and user group of the /dev/acache device.
Set acache_client to start upon system boot.
```
sudo systemctl enable acache_client
```
You can disable the automatic startup if necessary.
