--- Comment #1 from Jamie Gritton <ja...@freebsd.org> ---
I'm not surprised such a thing wouldn't work. The IPv6 jail-related kernel
code knows only IP addresses, and doesn't touch scope. These scoped link-local
addresses are a little beyond me I must admit*, but I can see at least one
essential jail concept breaking down in that paradigm: any IP communication of
the jail with itself is forcibly rerouted to localhost - which in the IPv6 case
kind of assumes the global scope where ::1 lives. I'm sure there are many
other ways that are a good less simple that the whole scope concept just
doesn't make it into the part of the kernel that knows/cares about jails.
I imagine it would take a lot of support deep in the IPv6 code to make jails
work on link-local addresses, and frankly I just don't see than happening. And
I wonder if it would be a good idea anyway - shunting a link-local address off
to a jail sounds it like could break things that depend on such addresses
existing in a regular non-jailed way.
(* It's also beyond me why a committee of people who know networking much
better than I do ever though such an abomination as this out-of-band special
"scope" address should even exist, but I digress).
