Either the documentation for exports or the parsing being done is incorrect.

According to the examples in exports(5), I should be able to do the following...

/usr /usr/local -maproot=0:10 friends

.. in exports, and it should work.

What I tried (just as an experiment):

optimus# cat /etc/exports 
/scratch	-alldirs -maproot=nobody
/store		-alldirs -maproot=nobody
/var /usr	-alldirs -maproot=nobody

What I got however was /var and /usr aren't being exported:

optimus# showmount -e
Exports list on localhost:
/store                             Everyone
/scratch                           Everyone

According to /var/log/messages from syslog it was a bad "line" in exports:

Aug 24 14:28:00 optimus mountd[686]: bad exports list line /var /usr

I'm not sure if this is a documentation issue or a functional issue, but the fact is that the 2 items don't align with one another.

echo "/var /usr	-alldirs -maproot=nobody" >> /etc/exports && killall -HUP mountd
