In Trusted Extensions, shared files can ease administration, and provide efficiency and speed. MAC is always in force.
Share single-level datasets from a labeled zone, over NFS – As in Oracle Solaris, shared directories ease administration. For example, you can install the man pages for Oracle Solaris on one system, and share the man page directory with other systems.
Share multilevel datasets from the global zone, over LOFS – LOFS-mounted datasets provide efficiency and speed when moving files from one label to another. Files are moved within the dataset, so no i/o operations are used.
Share multilevel datasets from the global zone, over NFS – An NFS server can share a multilevel dataset that contains files at many labels to many clients. Such a configuration eases administration and provides a single location for file distribution. You do not require a server at a particular label to serve clients at that label.
