Alexander Motin 0b0c76bc58 MFV r331695, 331700: 9166 zfs storage pool checkpoint 
illumos/illumos-gate@8671400134

The idea of Storage Pool Checkpoint (aka zpool checkpoint) deals with
exactly that.  It can be thought of as a “pool-wide snapshot” (or a
variation of extreme rewind that doesn’t corrupt your data).  It remembers
the entire state of the pool at the point that it was taken and the user
can revert back to it later or discard it.  Its generic use case is an
administrator that is about to perform a set of destructive actions to ZFS
as part of a critical procedure.  She takes a checkpoint of the pool before
performing the actions, then rewinds back to it if one of them fails or puts
the pool into an unexpected state.  Otherwise, she discards it.  With the
assumption that no one else is making modifications to ZFS, she basically
wraps all these actions into a “high-level transaction”.
