IP addresses and wildcards can be used when specifying host targets in exports.
User names are not valid exports options, save for the anon option which utilizes a local system UID or user
name (i.e. no user name mapping or resolution is performed.)
The highest level in the filesystem that can be specified for an export is the volume level. Implicitly this means
that each volume must be exported separately.
An export provides access to paths below the export, implying that multiple paths on the same volume can be
exported from an export.
