[Buildroot] [RFD] IPv6 ....

[W.P.]

Hi there,
I am a bit ... with options in buildroot "require IPv6".
And what if USER does NOT want to enable / build IPv6?

If he/she relies only on IPv4?

In "regular" Linux distributions (like mine, Fedora 16), there is NO 
easy way to get rid of IPv6. Except deleting all ipv6 related stuff from 
/lib/modules....

Why?
What for?

I know advantages of IPv6, but what "regular ISP" provides this?

W.P.
