The crossmnt and nohide options work correctly so long as security negotiation isn't required to cross the mount point (whether the mount command provides the correct set of security flavors or not). If the crossmnt export option is provided in this case (whether or not nohide is specified on the child export), an ls of the /mnt/home ends up with the results from an ls of /mnt. If the crossmnt option is not specified on the parent but nohide is specified on the child, an ls -l of /mnt results in slightly different contents while an ls -l of /mnt/home results in the contents of the hidden directory on the parent export. These behaviors seem undesirable, but perhaps not worth eliminating since they do represent something unsupported by the old format which is deprecated in favor of the new format where everything works just fine.
