    (description
     "The @acronym{WebDAV, Web Distributed Authoring and Versioning} 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 (@command{cp}, @command{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.")

    (description
     "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 @dfn{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 @emph{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!")

    (description
     "Libeatmydata transparently disables most ways a program might force data
to be written to the file system, such as @code{fsync()} or @code{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, @emph{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 @file{libeatmydata.so} to
the @env{LD_PRELOAD} environment of such tasks will override all C library data
synchronisation functions with custom @i{no-op} ones that do nothing and
immediately return success.

A simple @command{eatmydata} script is included that does this for you.")

more commonly known as xfstests, comprises over 1,500 tests that exercise
(@dfn{torture}) both the user- and kernel-space parts of many different file

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.
