Binary package “e2fsprogs” in ubuntu maverick
ext2/ext3/ext4 file system utilities
The ext2, ext3 and ext4 file systems are successors of the original ext
("extended") file system. They are the main file system types used for
hard disks on Debian and other Linux systems.
This package contains programs for creating, checking, and maintaining
ext-based file systems, and the generic fsck wrapper.
