Promotes a clone file system to no longer be dependent on its "ori-
gin" snapshot. This makes it possible to destroy the file system that
the clone was created from. The clone parent-child dependency rela-
tionship is reversed, so that the origin file system becomes a clone
of the specified file system.
What you will lose in the process is the snapshot history between the
'pre whoops' snapshot and 'now.' (After recreating the state of 'now'
in the clone of 'pre whoops' (less the accidental removals) via rsync,
for example.)
