Since the client knows the snapshot involved, it could give the correct
name to the process (/fs/.zfs/snapshot/<name>).

Also, you can rename snapshots.  A script could make sure that the most
recent snaphot is always called 'current' or something.  You place that
name on the backup list of the profile.  Then when it's time to rotate,
the script could rename 'current' to a timestamp and create a new
'current'.

Or maybe rotate like netapp 'daily.0' -> 'daily.1' etc...
