It's just example. it's not matter to support compressed or not. > >> So does it have any plan to support this feature at btrfs? > You can create file-backed loop device, mount it and copy the directory > contents there. Than unmount the loop and voila - you have btrfs image Right, I used it now, but some build machine doesn't have or support btrfs, it mean can't mount btrfs as loopback. I just want to create btrfs image from directory without any host machine dependency such as kernel version and whatever. To simply, just use the mkfs.btrfs itself.
