The native datastore works fine so far for me. Nice work!
Do I read the code right that it's currently only using the first
location in storeFiles? Is there intent to change that? Personally, I
don't care, but if we're moving to "one store, one location", it
should be documented ...

Is there an easy way to move data from one (old) store to another
(new)? I tried running two nodes, the old one as normal, and the new
one (i.e. empty routing table) transient with only the old node in its
seednodes. Then I requested tons of stuff through the new node. I
would have wanted it to get its data from the old node's store.
Unfortunately, fred is too smart for me, learns of other nodes very
fast, and thus routes request through the old node relatively rarely.
I'm going to try firewalling the new node.
Is there a better way?

Hmm, better diagnostics if your storeType does not match what you have
would be nice. Something like this, perhaps?
