OpenZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the OpenZFS community.

This package provides the statically-linked bcachefs from a minimal bcachefs-tools package. It is meant to be used in initrds.

GlusterFS is a distributed scalable network file system suitable for data-intensive tasks such as cloud storage and media streaming. It allows rapid provisioning of additional storage based on your storage consumption needs. It incorporates automatic failover as a primary feature. All of this is accomplished without a centralized metadata server.

fscryptctl is a low-level tool written in C that handles raw keys and manages policies for Linux filesystem encryption, specifically the fscrypt kernel interface which is supported by the ext4, f2fs, UBIFS, and CephFS filesystems.

This package provides the bcachefs command-line tool with many subcommands for creating, checking, and otherwise managing bcachefs file systems. Traditional aliases like mkfs.bcachefs are also included.

Bcachefs is a CoW file system supporting native encryption, compression, snapshots, and (meta)data checksums. It can use multiple block devices for replication and/or performance, similar to RAID.

In addition, bcachefs provides all the functionality of bcache, a block-layer caching system, and lets you assign different roles to each device based on its performance and other characteristics.

Gocryptfs is an encrypted overlay filesystem written in Go. It features a file-based encryption that is implemented as a mountable FUSE filesystem.

Gocryptfs was inspired by EncFS and strives to fix its security issues while providing good performance. Gocryptfs is as fast as EncFS in the default mode and significantly faster than paranoia mode in EncFS, which provides a security level comparable to Gocryptfs.

On CPUs without AES-NI, gocryptfs uses OpenSSL through a thin wrapper called stupidgcm. This provides a 4x speedup compared to Go's builtin AES-GCM implementation.

This package provides an implementation of the exFAT file system, including command-line tools to validate exFAT file systems and to create new ones.

httpfs2 is a fuse file system for mounting any HyperText (HTTP or HTTPS) URL. It uses HTTP/1.1 byte ranges to request arbitrary bytes from the web server, without needing to download the entire file. This is particularly useful with large archives such as ZIP files and ISO images when you only need to inspect their contents or extract specific files. Since the HTTP protocol itself has no notion of directories, only a single file can be mounted.

The WebDAV extension to the HTTP protocol defines a standard way to author resources on a remote Web server. Davfs2 exposes such resources as a typical file system which can be used by standard applications with no built-in support for WebDAV, such as the GNU coreutils (cp, mv, etc.) or a graphical word processor.

Davfs2 works with most WebDAV servers with no or little configuration. It supports TLS (HTTPS), HTTP proxies, HTTP basic and digest authentication, and client certificates. It performs extensive caching to avoid unnecessary network traffic, stay responsive even over slow or unreliable connections, and prevent data loss. It aims to make use by unprivileged users as easy and secure as possible.

However, davfs2 is not a full-featured WebDAV client. The file system interface and the WebDAV protocol are quite different. Translating between the two is not always possible.

mergerfs-tools is a suite of programs that can audit permissions and ownership of files and directories on a mergerfs volume, duplicates files and directories across branches in its pool, find and remove duplicate files, balance pool drives, consolidate files in a single mergerfs directory onto a single drive and create FreeDesktop.org Trash specification compatible directories.

Squashfuse lets you mount SquashFS archives in user-space. It supports almost all features of the SquashFS format, yet is still fast and memory-efficient.

Watcher may be used as a library or a program that can be used to efficiently watch a file system for changes. This package provides the following components:

include/wtr/watcher.hpp

C++ header library

watcher-c

C shared and static library

wtr.watcher

Command-line interface (CLI)

tw

Minimal, more human-readable CLI variant

Autofs is a kernel-based automounter for use with the Linux autofs4 module. It automatically mounts selected file systems when they are used and unmounts them after a set period of inactivity. This provides centrally-managed, consistent file names for users and applications, even in a large and/or frequently changing (network) environment.

Libeatmydata transparently disables most ways a program might force data to be written to the file system, such as fsync() or open(O_SYNC).

Such synchronisation calls provide important data integrity guarantees but are expensive to perform and can significantly slow down software that (over)uses them.

This price is worth paying if you care about the files being modified---which is typically the case---or when manipulating important components of your system. Please, do not use something called ``eat my data'' in such cases!

However, it does not make sense to accept this performance hit if the data is unimportant and you can afford to lose all of it in the event of a crash, for example when running a software test suite. Adding libeatmydata.so to the LD_PRELOAD environment of such tasks will override all C library data synchronisation functions with custom no-op ones that do nothing and immediately return success.

A simple eatmydata script is included that does this for you.

This package provides the bcachefs command-line tool with many subcommands for creating, checking, and otherwise managing bcachefs file systems. Traditional aliases like mkfs.bcachefs are also included.

Bcachefs is a CoW file system supporting native encryption, compression, snapshots, and (meta)data checksums. It can use multiple block devices for replication and/or performance, similar to RAID.

In addition, bcachefs provides all the functionality of bcache, a block-layer caching system, and lets you assign different roles to each device based on its performance and other characteristics.

This is a file system client based on the FTP File Transfer Protocol.

The FSQA regression test suite, more commonly known as xfstests, comprises over 1,500 tests that exercise (torture) both the user- and kernel-space parts of many different file systems.

As the package's name subtly implies, it was originally developed to test the XFS file system. Today, xfstests is the primary test suite for all major file systems supported by the kernel Linux including XFS, ext4, and Btrfs, but also virtual and network file systems such as NFS, 9P, and the overlay file system.

The packaged check script is not in PATH but can be invoked with the included xfstests-check helper.

BEES is a block-oriented, user-space deduplication agent designed for large btrfs file systems. It combines off-line data deduplication with incremental scanning to minimize the time your data spend on disk between being written and being deduplicated.

APFS-FUSE is a read-only FUSE driver for the Apple File System (APFS). It is currently in an experimental state — it may not be able to read all files, and it does not support all the compression methods in APFS.

The file command is a file type guesser, a command-line tool that tells you in words what kind of data a file contains. It does not rely on filename extensions to tell you the type of a file, but looks at the actual contents of the file. This package provides the libmagic library.

Geierlein is a free Elster client, i.e. an application that sends VAT declarations to Germany's fiscal authorities.

Currently it is *not* possible to send returns that are due annually (especially the income tax return) since the fiscal authority doesn't allow doing that off the ERiC library (which is proprietary however). It's not clear at the moment whether one day it will be possible to do so.

The package provides library functionality for communicating with a U2F device over USB.

Emacs-beancount is an Emacs mode for the Beancount accounting tool.

trezor is a Python library for communicating with TREZOR Hardware Wallet.
