Also I've been same worry about this. But ezjail also worked
in 12.0-CURRENT and almost everything stuffs used in that
except below:

(1) `jail_JID_devfs_ruleset' must be specified by number but
  name like

export jail_desktop_devfs_ruleset=11

(2) Additional parameters shoule be specified by
  `jail_JID_parameters' with semicolon separated list like

export jail_desktop_parameters="allow.kmem; allow.sysvipc;"

(3) If you through ICMP packets, set

jail_JID_socket_unixiproute_only="NO"

But now basically FreeBSD does not supprt variable based
specification like ezjail but jail.conf configuration. So
jail spit warning whenever start/restart:

root@kx:~ # service ezjail restart mail
Stopping jails: mail.tfc.
Starting jails: mail.tfc.
/etc/rc.d/jail: WARNING: Per-jail configuration via jail_* variables  is 
obsolete.  Please consider migrating to /etc/jail.conf.

Reinstalling all packages?
So you didn't just move jails from one host to another but you upgraded 
them to 11.0 also?
Because I had feeling that you want just to move them to another 
machine. And if you just move them (completely with shared basejail) you 
don't need to reinstall packages.


As Oliver said you can use rsync to transfer them without need to 
compress + scp + uncompress. It is much faster transfer than making 
archives.

Oliver,

I do appreciate you took the time to respond to my question. However,
when I asked how to move my ezjail-based jails, I meant exactly that.
I did not ask which is the best jail management system (for my use case
I'm completely fine with ezjail), or about the good and bad things
about ZFS (I have hardware RAID controller which can't do JBOD on this
server), or advantages of rsync over scp (doesn't make much difference
for one-time transfer of single .tar.gz file over LAN).

Now, to give answer to my own question: everything works fine, after -
of course - reinstalling all the packages with `pkg-static upgrade -f'.

Regards,

The github page says:

**No longer supported. iocage is being rewritten in a different
  language.

I would switch them to iocage+zfs, ezjail is sooo 90s. :)
Have a look at the documentation:
http://iocage.readthedocs.io/en/latest/basic-use.html

All jail settings are stored within ZFS properties so an upcoming
migration would only need a zfs send | zfs receive.

Further I would recommend to use rsync -av instead of scp.

moving ezjail-based jails from 10.3 host to 11.0 host

2016-10-17 Thread Marko Cupać 
Hi,

I have 10.3 host which runs a dozen or so ezjail-based jails. I have
installed another 11.0 host, and I'd like to move jails to it.

Can I just archive jails on 10.3, scp them to 11.0, and re-create them
there by restoring from archive (-a switch)?

Are there any additional actions I should perform?

Thank you in advance,
