The nfs.te file contains declarations for types used for files from an NFS server. At the end of the file, several rules are specified to define relationships among these NFS file types.
The nfs_t type is the default type for NFS file systems and their files. A separate type can be defined for the files provided by each NFS server, as described in Section 7.3. The nfs_clipper_t type is an example type for NFS files mounted from a host named clipper. Currently, both of these types can be read and written by all domains.
