10.6. Network File System

From the Red Hat Linux Reference Guide:
NFS (Network File System) allows hosts to mount partitions on a remote system and use them as though they are local file systems. This allows the system administrator to store resources in a central location on the network, providing authorized users continuous access to them.
In Fedora, the nfs-utils package is required for full NFS support. Run rpm -q nfs-utils to see if the nfs-utils is installed. If it is not installed and you want to use NFS, run the following command as the root user to install it:
yum install nfs-utils

10.6.1. NFS and SELinux

When running SELinux, the NFS daemons are confined by default. SELinux policy does not allow NFS to share files by default. If you want to share NFS partitions, this can be configured via the nfs_export_all_ro and nfs_export_all_rw Booleans, as described below. These Booleans are however not required when files to be shared are labeled with the public_content_t or public_content_rw_t types. NFS can share files labeled with these types even if the nfs_export_all_ro and nfs_export_all_rw Booleans are off.
