Hi Mike,

One thing I forgot to mention is my use of autofs.  The stub mountpoint exists 
even
if not nfs-mounted.

The solution may be to just use --exclude and make sure that all nfs autofs 
mounts
occur in the excluded directory.  The  --exclude-if-present option is 
interesting, but
I don't think it will work with autofs since the directory entry appears even 
if not
mounted.

Thanks for the suggestions!
Lew
