jail2 is an alternative rc script for jails, relying on jail.conf
instead of rc.conf variables. Additionally, ZFS integration is provided.
In contrast to the default jail rc script this one can run inside jails,
allowing the configuration of hierarchical jails.

X# Alternative rc script for jails. This script relies on
X# /etc/jail.conf instead of rc.conf variables. Usage:
X#
X# jail2_enable -> Enables the script
X# jail2_list -> List of jails to be started. The names
X# must match the names in /etc/jail.conf
X# jail2_$name_zfs -> List of ZFS datasets to connect to the
X# jail $name.
X#
X# To manage ZFS datasets within a jail the dataset must have
X# set the parameter "jailed" to 1. Additionally the jail must
X# have set the proberties "allow.mount", "allow.mount.zfs"
X# and "enforce_statfs" to value lesser than 2.
