I tried the following and not sure how to proceed; the ORIGIN of default and
defaultCleaned swaps as I promote them, and I cannot destroy the snapshot in
this state unless passing -R. I'm not sure if promoting defaultCleaned followed
by recursive destroy of the zfs snapshot is a good idea?

# bectl create defaultCleaned
# bectl list -a
