See:

6625930 ndd -get /dev/ip <if>:ip_forwarding sends warning to console, not 
terminal where command was issued

... for an example of a warning of that nature ending up in the bug 
database.  In retrospect, I should have implemented something to allow 
ndd to print a warning to the caller's stdio.
