I think I see the problem, and if this works, you'll probably crap
yourself--it's one I had to deal with a long time ago.  (It Just Hit Me,
much in the way a Pan-Galactic Gargle Blaster hits like a gold brick with a

*ALMOST* everything here is consistent.  -alldirs is only on things that are
actually fstab partitions, and nearly all of the exports are actually mount
points.

However, /export is the only mount point for all of /export, /export/X11,
and /export/local; likewise, /usr is the only mount point for both /usr and
/usr/share.  The problem is that these groups don't have the same export
options.

While it may sound insane, multiple directories under one mount point
_must_be_exported_with_precisely_the_same_hosts_and_options_.  I know this
deficiency has been pointed out before, and it is not one I know how to fix.  
Why this manifests as an error on a _different_ /etc/exports line in the
error message is beyond me.

Please change the following in the old exports setup as below, and let me
know if it works.  If so, feel free to file a PR with the additional
information above, requesting that nfs be fixed to allow different export
options on different subdirectories.

	/usr/share	defender.starwolf.com
	/export		-maproot=0 defender.starwolf.com
