Could you please confirm if I understood it correctly?Correct. You need the data in the root of the jail to boot, if you then attribute this dataset to the jail, it will vanish until "zfs mount -a" is run (rc script inside the jail). As it will vanish during the boot of the jail (if added automatically), the rc script to mount all datasets can not be found.[...]I think what you are trying to tell here is, unless and until that "vanished" dataset is put to use (mounted) from inside the jail, it will remain vanished/unusable from the host itself; however, once that dataset is put to use, the host system should be able to "see" and maybe even work on that dataset. Could you please confirm if I understood you correctly?Correct. A sub-dataset which is not needed to boot, or a dataset not within the subtree of the jail (and not needed to boot) can be used.Thank you for this information! If it is somewhere in the docs it is well hidden to me :)
I don't expect it to be in the docs. I try to come up with something for the man page for zfs (for the "attach to jail" part), but anyone shall feel free to beat me with this.
Anyone with an idea where in the jail man page we should add something too (I only had a look at the zfs man page when this issue came up)?
