Blockstore wishlist
- The ability to grow (shrink?) a persistent blockstore. See ops.emulab.net:~mike/blockstore-growing.txt for notes on how I did this manually once.
- The ability to promote an ephemeral blockstore to a persistent one.
- The ability to replace a blockstore with one of its clones (i.e., to essentially update the real blockstore with the contents of a clone).
- The ability to promote a clone to being its own independent blockstore.
The last two are from @kwebb.
