Ensure rcnfs service is not in use

SrednjaNivo 1Automatskaaix

Opis

The rcnfs entry starts the NFS, NIS and automount daemons during system boot. Additionally, it automounts filesystems with the attribute vfs = nfs. NFS is a service with numerous historical vulnerabilities and should not be enabled unless there is no alternative. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
