zfs
===

Manage ZFS properties, create, destroy and rollback snapshots, jail and unjail datasets (ZFS only),
and check ZFS usage for targeted jail(s).

Snapshot Management
-------------------

Bastille has the ability to create, destroy, and rollback snapshots when using ZFS. To create a snapshot,
run ``bastille zfs TARGET snapshot``. This will create a snapshot with the default ``bastille_TARGET_DATE``
naming scheme. You can also specify a TAG to use as the naming scheme, such as ``bastille zfs TARGET snapshot mytag``.
Bastille will then create the snapshot with ``@mytag`` as the snapshot name.

Rolling back a snapshot follows the same syntax. If no TAG is supplied, Bastille will attempt to use the
most recent snapshot following the default naming scheme above. To rollback a snapshot with a custom tag, run
``bastille zfs TARGET rollback`` or ``bastille zfs TARGET rollback mytag``.

To destroy a snaphot however, you must supply a TAG. To destroy a snapshot, run
``bastille zfs TARGET destroy mytag``.
