Jailrc is an improved startup/shutdown script for FreeBSD jails.

It contains the following changes to the original /etc/rc.d/jail script:

- parameters support: you can specify parameters supported by jail(8)	
- ZFS support: you can deletate ZFS datasets to jails
- jails are not identified by a file in /var/spool/jail anymore
- two new commands "create" and "remove" to manage persistent jails

To start jails with the jailrc script instead of /etc/rc.d/jail, use
instead of jail_enable="YES" the keyword jailrc_enable="YES".

------------------------------------------------------------------
Jailrc reads all settings supported by /etc/rc.d/jail
(see /etc/defaults/rc.conf) and the following additional settings:

jail_example_name=""		# Set to desired jail name
				# defaults to the name in "jail_list"
jail_example_persist=""		# Set to YES to create a persistent jail
jail_example_params=""		# Space-separated list of additional
				# user-supplied parameters for jail(8)
jail_example_zfs=""	# Space-separated list of ZFS datasets to be
			# managed from this jail. For proper operation,
			# allow.mount=1 and enforce_statfs=1 (or 0)
			# must be added to jail_example_params.
			# The "jailed" property must be set to "on"
			# on desired datasets before starting the jail.

------------------------------------------------------------------
Example rc.conf configuration with IPv4, IPv6 and a fixed jail ID:

jail_enable="NO"
jailrc_enable="YES"
jail_list="test"
jail_test_hostname="test.bb.cc"
jail_test_rootdir="/jail/test"
jail_test_ip="192.168.0.2,2001:db8:2:1::2"
jail_test_devfs_enable="YES"
jail_test_params="jid=8 enforce_statfs=1 allow.raw_sockets=1"

------------------------------------------------------------------
To enable the ZFS device (/dev/zfs) in jails, add the following lines
to your devfs.rules configuration file:

[devfsrules_jail_zfs=5]
add include $devfsrules_jail
add path zfs unhide
