Answer

The host-dir access with "/" path is needed to access Linux utility packages like iscsi-tools.

Additional Information

Runinng kubectl get daemonset -n <namespace> -o yaml shows the parameters:
...
hostPath:
        path: /sys
        type: Directory
        name: sys-dir
hostPath:
        path: /
        type: Directory
        name: host-dir
...


Modifying the parameter is not recommended and will cause mount issues as iscsi-tools will be inaccessible:
