>Description:
If you export two directories via NFS with similar names, IE: both the
same except for one has some extra characters at the end:

Example:  /usr/nfs
	  /usr/nfsshare

Clients will not be permitted to mount /usr/nfsshare.  If you place them
both on the same line, or comment out the first, the second will be
allowed.  My guess is that this has something to do with the 
subdirectory-checking code.
>How-To-Repeat:
Create two directories anywhere, say: /usr/nfs and /usr/nfsshare
and export them both.  Then try to mount /usr/nfsshare on another client.
It will fail.  Comment out the /usr/nfs line and try again (after 
restarting mountd) and you will be able to mount it.
>Fix:
Workaround: If you need to mount them both to one set of clients, put
them on the same line, otherwise, no solution.
