I know `mkfs.btrfs -r $rootdir` copies whatever in $rootdir to the newly created filesystem. When I try to use it for a block device, it creates a "minimal" filesystem which can only be mounted read-only. When I use it for an (qemu raw) image, it seems to work but it also gives: ERROR: device scan failed 'test.img' - Block device required in the process. So what is it supposed to be used with? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
