Yes, you lost. My changes did that. You are the second to hit it. Your kernel does not have "FEATURES()" present and the new user space that came a couple of days later expect it and disable your IPv4 because of that. The real problem is when people update the kernel, then update world and then figure out they need to go back to kernel.old. I'll add an UPDATING entry. You need an old user land or a new kernel to recover. > I have both INET and INET6 built into my kernel and userland, but > my immediate upstream router only supports IPv4 right now.
