.Sh DESCRIPTION
|

.Bl -tag -width ""
|

|
|
.Nm zfs
|
|
.Cm zone
|
|

|

|
|
Attach the specified
|
|
.Ar filesystem
|
|
to the user namespace identified by
|
|
.Ar nsfile .
|
|
From now on this file system tree can be managed from within a user namespace
|
|
if the
|
|
.Sy zoned
|
|
property has been set.
|
|
.Pp
|
|
You cannot attach a zoned dataset's children to another user namespace.
|
|
You can also not attach the root file system
|
|
of the user namespace or any dataset
|
|
which needs to be mounted before the zfs service
|
|
is run inside the user namespace,
|
|
as it would be attached unmounted until it is
|
|
mounted from the service inside the user namespace.
|
|
.Pp
|
|
To allow management of the dataset from within a user namespace, the
|
|
.Sy zoned
|
|
property has to be set and the user namespaces needs access to the
|
|
.Pa /dev/zfs
|
|
device.
|
|
The
|
|
.Sy quota
|
|
property cannot be changed from within a user namespace.
|
|
.Pp
|
|
After a dataset is attached to a user namespace and the
|
|
.Sy zoned
|
|
property is set,
|
|
a zoned file system cannot be mounted outside the user namespace,
|
|
since the user namespace administrator might have set the mount point
|
|
to an unacceptable value.

dataset to a user namespace identified by user namespace file
