To make context mounts persistent across remounting and reboots, add entries for the file systems in /etc/fstab or an automounter map, and use the desired context as a mount option. The following example adds an entry to /etc/fstab for an NFS context mount:

server:/export /local/mount/ nfs context="system_u:object_r:httpd_sys_content_t:s0" 0 0

Refer to the Red Hat Enterprise Linux 5 Deployment Guide, Section 19.2. "NFS Client Configuration" for information about mounting NFS file systems.
