> Description:
If a kernel built without IPv6 support then /etc/rc.d/jail fails to run with an \
error: "unknown parameter: ip6". This very longstanding bug already fixed in the 9.x \
branch but still exists in the 8.x while patch is available: \
http://lists.freebsd.org/pipermail/freebsd-jail/2012-November/001984.html

I have attached actual patch for 8.4 to this PR. Any chance to see this bug fixed \
after all? Say, in the 8.4-RELEASE-p4?

> How-To-Repeat:
Rebuild kernel with INET6 option commented out and try to run a /etc/rc.d/jail \
script.
> Fix:
Apply attached patch.
