Yes. There are various degrees of how close the journal is to the commit. One option is: the commit is preserved 1:1. The other extreme is: moves are fully converted to add+remove. But there are options in the middle, for example if the original operation included "move /a /b", and the journal wouldn't return it 1:1, but instead "add /b, then move /a/x to /b/x, and remove /a". I thought this is what the MicroKernelImpl does in some cases (if there are multiple operations), and I don't think it's a problem. Regards, Thomas
