This package provides the Linux kernel module for Bcachefs.

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.

GPhotoFS is a FUSE file system module to mount your camera as a file system on Linux. This allow using your camera with any tool able to read from a mounted file system.

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.

This package provides statically-linked jfs_fsck command taken from the jfsutils package. It is meant to be used in initrds.

This package provides several command-line tools to transform a supported file system, such as XFS, into one of a different supported type, such as ext4. All existing file contents, names, and directories are preserved.

The conversion happens in place, without the need to create a complete copy of the original data. This lets you transform almost full file systems on systems where adding (sufficient) additional storage space is not an option.

Do not use this package when you could simply create an empty file system from scratch and restore from a back-up. Transformation is limited, slow, and significantly increases the risk of irreversible data loss!

These are command-line user space tools for the exFAT file systems. Included are mkfs.exfat to create (format) new exFAT file systems, and fsck.exfat to check their consistency and repair them.

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.

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.

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.

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.

LIBNFS is a client library for accessing NFS shares over a network. LIBNFS offers three different APIs, for different use :

1. RAW, a fully asynchronous low level RPC library for NFS protocols. This API provides very flexible and precise control of the RPC issued.

2. NFS ASYNC, a fully asynchronous library for high level vfs functions

3. NFS SYNC, a synchronous library for high level vfs functions.

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.

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.

AVFS is a FUSE-based filesystem that allows browsing of compressed files. It provides the mountavfs command that starts a small avfsd daemon. When a specially formatted path under ~/.avfs is accessed, the daemon provides listings and content access on the fly. The canonical form of virtual file name is:

[basepath]#handler[options][:parameters][/internalpath]

Example file names:

• ~/.avfs/home/user/archive.tar.gz#ugz#utar/path/file

• ~/.avfs/#http:localhost|some|path

emacs-dired-hacks has dired-avfs module which enables seamless integration with avfs.

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.

NILFS is a log-structured file system supporting versioning of the entire file system and continuous snapshotting, which allows users to even restore files mistakenly overwritten or destroyed just a few seconds ago.

This package provides the user space component of CacheFiles, a caching back end that uses a directory on a locally mounted file system (such as ext4) as a cache to speed up (by reducing) access to a slower file system and make it appear more reliable.

The cached file system is often a network file system such as NFS or CIFS, but can also be a local file system like ISO 9660 on a slow optical drive.

CacheFiles itself is part of the kernel but relies on this user space cachefilesd daemon to perform maintenance tasks like culling and reaping stale nodes. Only one such daemon can be running at a time, and communicates with the kernel through the /dev/cachefiles character device.

This version modifies David Howells original cachefilesd---which appears unmaintained---to use the inotify API instead of the deprecated dnotify to monitor file changes.

This package provides Snapper, a tool that helps with managing snapshots of Btrfs subvolumes and thin-provisioned LVM volumes. It can create and compare snapshots, revert differences between them, and supports automatic snapshots timelines.

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

The JFSutils are a collection of utilities for managing the JFS, a 64-bit journaling file system created by IBM and later ported to the kernel Linux. The following commands are available:

1. fsck.jfs: check and repair a JFS file system or replay its transaction log.

2. logdump: dump the JFS journal log.

3. logredo: replay the JFS journal log.

4. mkfs.jfs: create a new JFS file system.

5. xchklog: save a JFS fsck log to a file.

6. xchkdmp: dump the contents of such a log file.

7. xpeek: a JFS file system editor with a shell-like interface.

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.

The proc filesystem is a pseudo-filesystem which provides an interface to kernel data structures. This package provides a means to query that system from a Python module. See proc(5) for more details.

RewriteFS is a FUSE to change the name of accessed files on the fly based on any number of regular expressions. It's like the rewrite action of many Web servers, but for your file system. For example, it can help keep your home directory tidy by transparently rewriting the location of configuration files of software that doesn't follow the XDG directory specification from ~/.name to ~/.config/name.
