ezjail and zfs in FreeBSD>=9.1

[Alexander Pyhalov]

Hello.
It seems that ezjail 3.3 doesn't set allow.mount allow.mount.zfs when 
delegates zfs fs to a jail.

Changing

# Attach ZFS-datasets to the jail
for zfs in ${ezjail_zfs_datasets}; do
  /sbin/zfs jail ${ezjail_id} ${zfs} || echo -n "Error: ${zfs} could not 
be configured"
done

to

# Attach ZFS-datasets to the jail
[ -z "${ezjail_zfs_datasets}" ] || /usr/sbin/jail -m jid=${ezjail_id} 
allow.mount allow.mount.zfs
for zfs in ${ezjail_zfs_datasets}; do
   /sbin/zfs jail ${ezjail_id} ${zfs} || echo -n "Error: ${zfs} could 
not be configured"
done

in /usr/local/etc/rc.d/ezjail

solves the issue for me.
