zerofree 1.1.1

Zero non-allocated regions in ext2/ext3/ext4 file systems

Zerofree finds the unallocated blocks with non-zero value content in an ext2, ext3, or ext4 file system and fills them with zeroes (or another value). This is a simple way to make disk images more compressible. Zerofree requires the file system to be unmounted or mounted read-only.

Installation

Install zerofree 1.1.1 as follows:

guix install zerofree@1.1.1

Or install the latest version:

guix install zerofree

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
