From 3048255235c13ee10b5110350ab5dde9d619ccd1 Mon Sep 17 00:00:00 2001 From: Devin Teske Date: Sun, 28 Oct 2018 18:32:47 +0000 Subject: Fix jail examples in jib, jng, README The provided example jail configs do not work for multiple interfaces. Multiple interfaces need to be specified as a comma separated list or using multiple += lines in jail.conf. In the given example, a space- separated string is used, which doesn't work with multiple interfaces. Also added a note to the README about VIMAGE being built-in by default on amd64 in FreeBSD 12, with appropriate instructions for loading the necessary netgraph ether module (ng_ether) since it is neither built- in nor autoloads.
