Personally I'm all for that.  I guess I was thinking too much about
backwards compatibility and not enough about bootstrapping.

This does raise the question of how far you are willing to let backwards
compatibility go - if it's "all the way" (on the theory that anyone who
has written a script that expects a certain output from config wouldn't
typically expect that script to be easily ported to a new OS anyway),
there are quite a few other aspects of config that could be cleaned up. 
Especially the way it reports errors (sometimes to stdout, sometimes to
stderr, sometimes with err, sometimes just with printf.)  I'd be happy
to take this on :)
