How does "allow building Linux to be IPv6-only" somehow "deny others their freedom" exactly? I'm willing to wager most distributions will still be dual v4+v6, but if they aren't, isn't that something for you to bring up with your distribution rather than that the kernel just allows something?
I have no problem with allowing optional IPv4 or IPv6 only builds as long as both are kept well-maintained.
But so what? It still doesn't remove v4, in any shape or form, and if that was proposed to the kernel, I'm again fairly confident it'd be rejected.
> I also see hostility towards IPv4 in the comments here and other similar discussions
Ah, yeah that might be. I just saw your comment first, with no context of what you were actually answering, so it kind of looks like you're replying "to the submission", which really isn't denying any freedoms, I guess I was confused about that, my bad. Still, wouldn't it be better to answer directly to those comments, rather than "replying" to an argument/debate that is actually happening elsewhere?
The reason that I don’t like seeing patches like this, even as a “joke”, is that there are real people who would like to see IPv4 removed (possibly by government intervention) in order to achieve their dream of an IPv6 only internet. The whole idea is preposterous, but here we are. It’s about as realistic as banning cars but that doesn’t stop the endless flame wars about it.
Someone has to step in to point out that v4 and v6 were designed to coexist, this is fine, please don’t remove common standards for your personal preferences.
You want IP4V, put it back. Should be a couple of minutes with diff and patch. You want IPV6 only, vi is available, get to it.
Ohhh.. You are concerned about the operating system given to you for free.
Get over it.
(my personal opinion is, ipv4 will be used for the next 100 years, but Open Source / GPL is about freedom)
Want to use IPv6? Fine. But don’t try to remove v4 support from people who have built stable networks around it.
You won’t be able to force the world to switch to IPv6 with tricks like this, any more than you can force old industrial machines to stop using ancient 486es as controllers. There is a lot of old equipment in the world.
IPv6 was built to work alongside v4, and there is no reason to change that.
