This + would also avoid the risks facing the current system, where the converter + notes where the data lives in the "inner" bcachefs image, and then the + content is moved out from under it (such as by GC, or btrfs rebalancing) * Support "adopting" devices, by importing their content _into_ an existing filesystem using the existing extents on the old device. In theory, could supplant "adding a cache" in a minimally-invasive way. |
