Jail-bound ZFS datasets still need the usual zfs+jail stuff like security.jail.mount_allowed=1 and security.jail.enforce_statfs=0 as well as "add path zfs unhide" in the devfs.rules for the jail.
The setfib utility requires FIBs to be enabled via kernel-config.
All features need at least FreeBSD 7.1-RELEASE.
ezjail is now capable of managing jails in seperate ZFS filesystems and to manage basejail and newjail in seperate ZFS filesystems too.
It is possible to mix non-ZFS jails with ZFS jails as well as using ZFS jails with basejail/newjail in a non-ZFS filesystem.
To create a zfs jail you need an existing ZFS pool, ZFS needs to be enabled in /etc/rc.conf and you have to set at least ezjail_jailzfs in ezjail.conf. To let ezjail manage basejail/newjail in ZFS filesystems to, you have to enable ezjail_use_zfs in ezjail.conf.
To use ZFS support in ezjail, you have to use at least FreeBSD 7-STABLE form after the commit of ZFS version 13 (commited Wed May 20 23:34:59 2009 UTC, http://svn.freebsd.org/viewvc/base?view=revision&revision=192498) of FreeBSD 8-CURRENT. Prior versions of ZFS are _not_ supported.
Creating a ZFS based jail is as easy as using 'ezjail-admin create -c zfs <jailname> <jailip>'.
Using zfs send/receive for archiving is not yet implemented.
Converting non-ZFS basejail/newjail setups into ZFS setups is not handled by ezjail, converting non-ZFS jails into ZFS jails is not yet handled by ezjail but will be possible in the future.
WARNING: ZFS is considered to be an experimental feature in FreeBSD. ZFS support in ezjail is work in progress.
Those commands can be used to add ports, sources and man page packages to an already installed base without reinstalling the base.
Unify error reporting and try to give the user enough clues as how to go on in case of an error.
Also put image size for image jails into the properties list.
Auto attach image jails for archive (if possible, aka non-blocking).
Actually call ezjail-admin create from ezjail-admin restore.
This means, that restore is rudimentary up and running.
