Is it possible to rebuild a DwarFS fs to incorporate changes from an overlay fs without decompressing, then recompressing?
It seems feasible that a second DwarFS fs could be built from an overlay/DwarFS, then delete the original overlay/DwarFS fs. That would require 2N storage as the new DwarFS is being built. Is it possible to patch an existing DwarFS?
By overlay, are you referring to overlayfs [0]?
