Description
The rcnfs entry starts the NFS daemons during system boot. NFS is a service with numerous historical vulnerabilities and should not be enabled unless there is no alternative. If NFS serving is required, then read-only exports are recommended and no filesystem or directory should be exported with root access. Unless otherwise required the NFS daemons (rcnfs) will be disabled.
