Mounting a ZFS dataset within a jail

[ghostdogg]

I'd like to create a jail to run the Docker daemon but unfortunately it refuses to run unless there is a ZFS dataset mounted on /usr/docker. ZFS datasets cannot be created within a jail because it requires a kernel module. I also tried mounting a dataset in FreeNAS to /usr/docker in the jail which doesn't work either. Is this just not possible without official support in FreeNAS? Running FreeNAS-9.10-STABLE-201606270534. Information about the freebsd docker port here.

Does adding a storage work, as described in http://doc.freenas.org/9.10/freenas_jails.html#add-storage? If not, what exact error do you get when you try to access the added storage?

Requirements
FreeBSD 11-CURRENT from July, 2015 or newer, specificially,

FreeNAS 9.10 is based on FreeBSD 10.3, therefore there is no Docker support.

Jail on FreeBSD is already what "container" is in Docker. I think Docker was modeled after FreeBSD jail system.

Thanks for the feedback. I'll wait for FreeNAS 10. I know jails have similar functionality to docker but I already have many containers that I would like to run and would like to not port them over to freebsd jails.
