Roll back the given dataset to a previous snapshot.

recursive : boolean
destroy any snapshots and bookmarks more recent than the one
specified.

destroy any more recent snapshots and bookmarks, as well as any
clones of those snapshots.
force : boolean
used with the -R option to force an unmount of any clone file
systems that are to be destroyed.
.. warning::
When a dataset is rolled back, all data that has changed since
the snapshot is discarded, and the dataset reverts to the state
at the time of the snapshot. By default, the command refuses to
roll back to a snapshot other than the most recent one.
In order to do so, all intermediate snapshots and bookmarks
must be destroyed by specifying the -r option.

Promotes a clone file system to no longer be dependent on its "origin"
snapshot.
.. note::
This makes it possible to destroy the file system that the
clone was created from. The clone parent-child dependency relationship
is reversed, so that the origin file system becomes a clone of the
specified file system.
The snapshot that was cloned, and any snapshots previous to this
snapshot, are now owned by the promoted clone. The space they use moves
from the origin file system to the promoted clone, so enough space must
be available to accommodate these snapshots. No new space is consumed
by this operation, but the space accounting is adjusted. The promoted
clone must not have any conflicting snapshot names of its own. The
rename subcommand can be used to rename any conflicting snapshots.
