We put configdrive with is9660 filesystem to a
partition on a hard disk. New hard disks may have
4K sectors, but blocksize of iso9660 fs is 2K so
it will not work.
To fix this bug we should use another filesystem (ext2)
and another config drive format (files, directory
structure), because NoCloud format, which is currently
used support only vfat and iso9660 filesystems.
