This patcheset fixes errors in virt-sysprep and virt-sparsify. Here we have a common functionality: is_btrfs_subvolume. Doesn't it make sense to turn it into guestfs API? Also I found an issue. In 'virt-sysprep fs-uuids', the uuids for ALL filesystems are regenerated as many times as many roots are in guest. Is it done intentionally? Maxim Perevedentsev (3): mllib: add checking
