From everything that I can tell, this is no deployment of .SIG between stub and recursive -- this is based upon the fact that I'd really *like* to be able to do this, and have spent some time looking into how, but no-one seems to know how to actually configure something to do this…

Running 'strings' on recover libraries *seems* to make it appear that the code exists, and asking folk who should know elicits "Oh, yeah, you add, um, something to /etc/resolve.conf… I think it is called 'tsig-ke..' um, no, it's 'key-tai…' um, yeah, I *think* this is doable, but I cannot remember at the moment *how*. I'll get back to you…"

Yes, I realize I could just go actually go read the source, spend some cycles looking at lwres, etc, but I'd rather simply kvetch [0]
