It's good for writing checkpoints of a tmpfs to non-volatile (NV)
storage in an embedded system where writing to the NV storage is costly
(it wears out, or it is slow, or both). When you have a snapshot, you
can stream it to NV storage using pax(1). This is the best practical
way that I can think of in NetBSD at this time.
