Really nice to see the new file systems addressing this issue, but, as many including me hurt by AUFS, I am being cautious. Do you think it is battle tested enough? As it is different than other merging ones, it is a little more dangerous than them as well since it works on block level? Not trying to be negative, I really liked it, and I am not even happy about even a docker load command performance over my overlay2, and will defintely be trying LCFS.
