If you didn't write it, I apologize for venting at the wrong person.

Any fusses I have posted to bugzilla have all been "won't fix" in just a

Ohkaay, but where's the docs on this mysterious resolvconf?
What we do have is missing (wheezy) or horribly incomplete (jessie).
But I'll have to take that back, my apologies. I just read the stretch
version on that rock64. And as man pages go, its decent. And I'll have
to do some experimenting as its possible I can train it to behave.
And curious I blink compared the jessie vs stretch versions, stretch's is
both longer AND more complete, and two different authors and formatted
completely different. And wheezy doesn't even have the man page. I don't
even know if it should, maybe not for wheezy, lots of water has been
recycled since those installs were made, so I'll plead oldtimers.
