pjd 410069d287 When zfs dataset has jailed=on property, it won't be mounted with
'zfs mount -a' from the main system - this is by design, as mountpoint
may be set to dangerous value. This all means, that such file system
has to be mounted from within a jail. To make it easier, reorganize
rc.d/zfs script so it can be used from within a jail.
