That's interesting. When adding IPv6 support to HAST I was thinking about making IPv4/IPv6 support compile options. But after discussing this with various folks I decided to always compile IPv4 and IPv6 support in for userland tools and detect what is supported by the kernel at runtime. This way it is easy to just recompile the kernel to add/remove IPv4/IPv6 support and userland tools may stay unmodified. Do we have some general recommendation within FreeBSD how to handle this in userland?
