Is this viable as a backup/archive format? Would it make sense to e.g. have an incremental backup as a DwarFS file, referring to the base backup in another DwarFS file?
I guess something like borgbackup would be better suited for this.
You could theoretically try to build this with dwarfs, by using overlayfs and then compressing the upper layer again with dwarfs, but that sounds pretty fragile and cumbersome.
