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.
