I don't like those particular strategy names very much, but in general
I think that could be a way to go, too. I somewhat hope we never end
up with THREE strategies for creating a new database, but now that I
think about it, we might. Somebody might want to use a fancy FS
primitive that clones a directory at the FS level, or something.
