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)?
It would be nice to have this mentioned in zfs(8) man page (that user
in jail cannot manage jail's root dataset but can manage some
sub-dataset not required to boot the jail)
What about this? Better wording welcome.

And there can be some useful example in jail(8) man page in EXAMPLES.
There is section "Jails and File Systems" and there can be new section
"Manage ZFS from within jail" with basic notes about required jail
params, zfs set jailed property and example "hierarchy". (and warning
about gotchas with jailed=0 on jail's root directory)
Are you willing to come up with some text-only version/draft/outline for
this one?
I am not good at English but I will try something.
Thank you!
