Comment 5 for bug 1674330

Hm, cosmic rays, my comment wasn't saved :/

I also did some testing and the only case that won't work without either the hook, or using the IP_FREEBIND socket option, is when ListenAddress is set to an IP that doesn't exist yet. Meaning, sshd won't listen on that IP when it comes up.

Maybe people caught in this corner case should use 0.0.0.0 (or the IPv6 equivalent) for ListenAddress and firewall rules to control which traffic can reach the sshd daemon. That's the only way in artful now anyway.
