Well, AFAIR ftp has been working this way at least since 2005 :-)
And this is not my local problem. Look at the output provided
by Takahiro Kambe.

Yes, and since then ftp(1)... :-)

This why I'd like to have a variable in rc.conf for disabling
configuring ipv6 on my network interfaces.

I have not analysed patch by Robert Elz yet, but
it is not complete (changes in etc/default/rc.conf and man page are missing).

If I cannot use it (yet), I don't see reasons to configure
it and have a garbage in stderr.
