To cinder driver developers:

· https://blueprints.launchpad.net/cinder/+spec/support-revert-to-any-snapshot

In relation to the blueprint above.  I am wondering if there are any drivers that whose later snapshots will not be valid after a revert to an snapshot that is NOT the last in the series

                                                              Vol1

                                                                 \

-----------------------------------------------------

Mon        Tue          Wed       Thu           Fri

   \              \                 \                \              \

    S1 -------- S2 ---------S3 -------- S4 ---------S5

If on Fri, I was to revert back to Tuesday’s Snapshot S2, would S3, S4 and S5 still be usable Snapshots?

             Vol1

Mon        Tue          Wed       Thu           Fri

    S1 -------- S2 ---------S3 -------- S4 ---------S5

Thank you,
