Yes, the "V4:" exports line needs to be
manually put in /etc/exports.

Note that it does not export any file system,
so you also need a line like:
/export_this      -sec=sys grumpy.cis.uoguelph.ca

either in /etc/exports or generated from the sharenfs
property by setting it without the "V4: /" component
in it.

Call it a bug or a feature, but since the "V4:..." line
does not refer to any file system, it does not work for
sharenfs. I doubt this will ever change.
(Also note that both /etc/exports and /etc/zfs/exports
are used by mountd when started via the rc.d scripts.
See /etc/rc.d/mountd.)
