This approach will work too. But it seems that asking fossil

if checksumming is a good idea, shouldn't it be available outside
fossil?
It is available -- in venti ;-)
perhaps the argument is that it might be more efficient
to implement this inside fossil.
The argument has nothing to do with the efficiency. However
the way fossil is structured -- I think you're right it won't be
able to get additional benefits from its own checksuming.
while this might be the case, i
don't see how the small overhead of a sd layer would matter
when you're assuming an ec2-style service, which will have a
minimum latency in the 10s of milliseconds.
Somehow you've got this strange idea that I'm engineering
something for ec2-style services. I am not. EC2 was a simple
example I used once. If it agitates you too much I promise
not too use it in the future ;-)
