nilfs-tools 2.2.8-1 (ppc64el binary) in ubuntu groovy

 NILFS is a new implementation of a log-structured filesystem. It allows
 continuous snapshotting, so that users can restore files mistakenly overwritten
 or destroyed even when it happens after the last backup.
 .
 This package contains utilities (mkfs, fsck, etc.) used to work with nilfs.
