Slax is a portable Linux operating system I am using in order to build LFS.
Please don't say `Linux operating system', it is unfair to those who actually wrote it, the GNU project. Linux is an important part of the GNU system, but it is not the system -- it is a kernel. You can help us spread that knowledge by talking about GNU when you talk about GNU-powered software distributions (a la GNU/Linux instead of just Linux). Please see http://www.gnu.org/gnu/linux-and-gnu.html for more information. So, you are telling me that if the operating system I am using does not support IPv6, the operating system I am trying to build also will not support it? Seeing that the operating system you are using is GNU/Linux, then it does support IPv6. But for whatever reasons, your kernel (Linux) can have IPv6 support disabled. Can you check? The directory /proc/sys/net/ipv6/ should exist with some files in it.
