Thanks Roy!

I kind of assumed from the changelog that the next release would quiet
the logging somewhat.

I wonder is this kind of "misconfiguration" common with (older?)
Linux-based firewalls?  (This one is ostensibly OpenWRT under the covers
-- they used to allow telnet to a command line, but removed it some
revisions ago.)  I really need to replace it I guess.

=46rom my understanding now of the options given in the router UI it
shouldn't be saying "DHCPv6 exists" when it is in the default
"auto configure" mode, but I guess for some reason it does.
