Author: dteske Date: Sun Oct 28 18:32:47 2018 New Revision: 339843 URL: https://svnweb.freebsd.org/changeset/base/339843 Log: 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.
