In general you do this with losetup(8) instead of in the filesystem itself, since the FS generally doesn't care about the block device. e.g. losetup -o 32768 .... > 2) Is there a / how do you patch the fs driver to allow for > transparent zlib decompression of the HFS+ volume (inside the DMG > file)? No idea. A device mapper target (or fuse-over-loopback) could do that but I don't know if there is something suitable already. -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
