Nilfs has once changed ioctl interface (ABI) to clean up architecture
dependency problems found in the review process of mainline merge.

The nilfs2-tools included in Ubuntu Jaunty is older than that.

Please download the latest util package (nilfs-utils-2.0.14) from

  http://www.nilfs.org/en/download.html

and use it instead.

The newer nilfs2-tools is available on karmic, but in either case it
seems to be less frequently updated than Debian.
