    .Xc
    Renames the given dataset.
    The new target can be located anywhere in the ZFS hierarchy, with the exception
    of snapshots.
    Snapshots can only be renamed within the parent file system or volume.
    When renaming a snapshot, the parent file system of the snapshot does not need
    to be specified as part of the second argument.
    Renamed file systems can inherit new mount points, in which case they are
    unmounted and remounted at the new mount point.
    .Bl -tag -width "-a"
    .It Fl f
    Force unmount any file systems that need to be unmounted in the process.
    This flag has no effect if used together with the
    .Fl u
    flag.
   .It Fl p
   Creates all the nonexistent parent datasets.
   Datasets created in this manner are automatically mounted according to the
   .Sy mountpoint
   property inherited from their parent.
   .It Fl u
   Do not remount file systems during rename.
   If a file system's
   .Sy mountpoint
   property is set to
   .Sy legacy
   or
   .Sy none ,
   the file system is not unmounted even if this option is not given.
   .El

   .Xc
   Recursively rename the snapshots of all descendent datasets.
   Snapshots are the only dataset that can be renamed recursively.

   .Sh EXAMPLES
   .\" These are, respectively, examples 10, 15 from zfs.8
   .\" Make sure to update them bidirectionally
   .Ss Example 1 : No Promoting a ZFS Clone
   The following commands illustrate how to test out changes to a file system, and
   then replace the original file system with the changed one, using clones, clone
   promotion, and renaming:
   .Bd -literal -compact -offset Ds
   .No # Nm zfs Cm create Ar pool/project/production
     populate /pool/project/production with data
   .No # Nm zfs Cm snapshot Ar pool/project/production Ns @ Ns Ar today
   .No # Nm zfs Cm clone Ar pool/project/production@today pool/project/beta
     make changes to /pool/project/beta and test them
   .No # Nm zfs Cm promote Ar pool/project/beta
   .No # Nm zfs Cm rename Ar pool/project/production pool/project/legacy
   .No # Nm zfs Cm rename Ar pool/project/beta pool/project/production
     once the legacy version is no longer needed, it can be destroyed
   .No # Nm zfs Cm destroy Ar pool/project/legacy
   .Ed
   .
   .Ss Example 2 : No Performing a Rolling Snapshot
   The following example shows how to maintain a history of snapshots with a
   consistent naming scheme.
   To keep a week's worth of snapshots, the user destroys the oldest snapshot,
   renames the remaining snapshots, and then creates a new snapshot, as follows:
   .Bd -literal -compact -offset Ds
   .No # Nm zfs Cm destroy Fl r Ar pool/users@7daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@6daysago No @ Ns Ar 7daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@5daysago No @ Ns Ar 6daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@4daysago No @ Ns Ar 5daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@3daysago No @ Ns Ar 4daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@2daysago No @ Ns Ar 3daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@yesterday No @ Ns Ar 2daysago
   .No # Nm zfs Cm rename Fl r Ar pool/users@today No @ Ns Ar yesterday
   .No # Nm zfs Cm snapshot Fl r Ar pool/users Ns @ Ns Ar today
