Agreed.  And I only recommend rebuilding the kernel, one of my
motivations for that is besides not needing the v6 on a log of
stuff is it reduces both wasted code size, and some security
concerns.

I also agree here, running a WITHOUT_IPV6 userland is both very painful
to get built AND has issues that one does not need to face, like I showed
in another thread about netstat -6.
