Description bartsch 2012-06-13 11:30:06 UTC 
In our environment (KERNCONF without INET6) /usr/sbin/jail fails, if one of the ip6 parameters is used. The error message is "jail: unknown parameter: ip6".

IMHO it would be the right way to simply ignore these parameters in a IPV4-only environment.

How-To-Repeat: create kernel without INET6
start jail after reboot with ip6=disable
Comment 1 Dewayne 2012-11-23 02:26:01 UTC 
This problem only affects people using jails built without IPV6.  The patch
below fixes the problem, and anticipates builds without IPv4 :)

My apologies, in advance for the line breaks that my mailer will insert.

The following patch is applied against 9-Stable built on 17th Nov 2012.
