New Revision: 249591
URL: http://svnweb.freebsd.org/changeset/base/249591

Log:
  Document jail_<jname>_parameters option.
  
  The description explains why we should not configure "path",
  "host.hostname", "command", "ip4.addr" and ip6.addr" parameters with
  this, but rather use the historical rc.conf(5) options.
