 The problem is that you are trying to export *two different* filesystems 
 in one line:
 
 /var /usr    -alldirs -maproot=nobody
 
 Have a better look at  the man page:
 
 "In a mount entry, the first field(s) specify the directory path(s) within
  a server file system that can be mounted on by the corresponding
  client(s)"
 
 The above would not work on a typical FreeBSD setup, where /usr and /var 
 are different filesystems
 The example in the man page correctly shows two different mount points 
 inside the *same* filesystem:
 
 /usr  /usr/local  -maproot=0:10 friends
 
 If you were to write this as two different lines, it would work:
 
 /var   -alldirs -maproot=nobody
 /usr  -alldirs  -maproot=nobody
 
 I don't see a documentation problem here.
