Using the exports file in 'How-to-repeat' section, I'm unable to get both
mount points exported. Only the first one listed will succeed, the second
entry will fail with messages (switching the dir paths of course):

Jun 27 23:58:53 enterprise mountd[208]: can't change attributes for /usr/ports
Jun 27 23:58:53 enterprise mountd[208]: bad exports list line /usr/ports -maproot

It doesn't make any difference which one comes first, it's always the second
one listed that fails. If I comment one of them out, then everything works
-- but I only have the one mountpoint exported ;(

I believe these should both work, according to exports(5).

Fix: 

I don't know, haven't looked to deeply into it yet.
How-To-Repeat: Try to start, or reload, mountd with the following exports file:

/usr/local/fbsd -maproot=spock -network 192.168.100 -mask 255.255.255.0
/usr/ports -maproot=root -network 192.168.100 -mask 255.255.255.0

Only the first mountpoint succeeds, the second one will always fail.

How's your filesystem layout?  Are /usr/local/fbsd and /usr/ports on
the same filesystem?  See:

Yea, I think I screwed up...hadn't noticed that FAQ. Thanks for pointing it out.

P.S. I'll close the pr up.

My own user error ;( 
For reference, there is a FAQ at: 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/networking.html#EXPORTS-ERRORS 
describing the problem.
