List the file systems that clients will be allowed to mount. All paths should be fully qualified. The exports table can include two types of element: a string element (as above), or an alternate table element form { path="/path", opts="ro" }. In the alternate form, the (optional) opts attribute is a comma-separated list of export options. The two table element forms can be mixed in the exports table. Note that although diod will not traverse file system boundaries for a given mount due to inode uniqueness constraints, subdirectories of a file system can be separately exported.
