You cannot export directories on the same kernel mountpoint with
different options.

If /usr or /home/client/{root,swap} are on the same mount, you must
export each directory with the same options. This is mentioned in the
exports(5) man page,

``
BUGS
     The export options are tied to the local mount points in the kernel and
     must be non-contradictory for any exported subdirectory of the local
     server mount point.
''

You can null mount directories as a workaround, see mount_null(8).
