+cdist-type__debian_backports(7)
+===============================
+
+NAME
+----
+cdist-type__apt_backports - Install backports
+
+
+DESCRIPTION
+-----------
+This singleton type installs backports for the current OS release.
+It aborts if backports are not supported for the specified OS or
+no version codename could be fetched (like Debian unstable).
+
+The package index will be automatically updated if required.
+
+It supports backports from following OSes:
+
+- Debian
+- Devuan
+- Ubuntu
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+state
+    Represents the state of the backports repository. ``present`` or
+    ``absent``, defaults to ``present``.
+
+    Will be directly passed to :strong:`cdist-type__apt_source`\ (7).
+
+mirror
+    The mirror to fetch the backports from. Will defaults to the generic
+    mirror of the current OS.
+
+    Will be directly passed to :strong:`cdist-type__apt_source`\ (7).
+
+
+BOOLEAN PARAMETERS
+------------------
+None.
+
+
+MESSAGES
+--------
+None.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+   # setup the backports
+   __apt_backports
+   __apt_backports --state absent
+   __apt_backports --state present --mirror "http://ftp.de.debian.org/debian/"
+
+   # install a backports package
+   # currently for the buster release backports
+   require="__apt_backports" __package_apt wireguard \
+        --target-release buster-backports
+
+
+ABORTS
+------
+Aborts if the detected os is not Debian.
+
+Aborts if no distribuition codename could be detected. This is common for the
+unstable distribution, but there is no backports repository for it already.
+
+
+CAVEATS
+-------
+For Ubuntu, it setup all componenents for the backports repository: ``main``,
+``restricted``, ``universe`` and ``multiverse``. The user may not want to
+install proprietary packages, which will only be installed if the user
+explicitly uses the backports target-release. The user may change this behavior
+to install backports packages without the need of explicitly select it.

 -----------
 Manages the list of keys used by apt to authenticate packages.
 
+This is done by placing the requested key in a file named
+``$__object_id.gpg`` in the ``keydir`` directory.
+
+This is supported by modern releases of Debian-based distributions.
+
+In order of preference, exactly one of: ``source``, ``uri`` or ``keyid``
+must be specified.
+
 
 REQUIRED PARAMETERS
 -------------------
@@ -18,21 +26,49 @@ None.
 
 OPTIONAL PARAMETERS
 -------------------
+keydir
+   keyring directory, defaults to ``/etc/apt/trusted.pgp.d``, which is
+   enabled system-wide by default.
+
+source
+   path to a file containing the GPG key of the repository.
+   Using this is recommended as it ensures that the manifest/type manintainer
+   has validated the key.
+   If ``-``, the GPG key is read from the type's stdin.
+
 state
    'present' or 'absent'. Defaults to 'present'
 
+uri
+   the URI from which to download the key.
+   It is highly recommended that you only use protocols with TLS like HTTPS.
+   This uses ``__download`` but does not use checksums, if you want to ensure
+   that the key doesn't change, you are better off downloading it and using
+   ``--source``.
+
+
+DEPRECATED OPTIONAL PARAMETERS
+------------------------------
 keyid
-   the id of the key to add. Defaults to __object_id
+   the id of the key to download from the ``keyserver``.
+   This is to be used in absence of ``--source`` and ``--uri`` or together
+   with ``--use-deprecated-apt-key`` for key removal.
+   Defaults to ``$__object_id``.
 
 keyserver
-   the keyserver from which to fetch the key. If omitted the default set
+   the keyserver from which to fetch the key.
-   in ./parameter/default/keyserver is used.
+   Defaults to ``pool.sks-keyservers.net``.
 
-keydir
-   key save location, defaults to ``/etc/apt/trusted.pgp.d``
 
-uri
+DEPRECATED BOOLEAN PARAMETERS
-   the URI from which to download the key
+-----------------------------
+use-deprecated-apt-key
+   ``apt-key(8)`` will last be available in Debian 11 and Ubuntu 22.04.
+   You can use this parameter to force usage of ``apt-key(8)``.
+   Please only use this parameter to *remove* keys from the keyring,
+   in order to prepare for removal of ``apt-key``.
+   Adding keys should be done without this parameter.
+   This parameter will be removed when Debian 11 stops being supported.

+cdist-type__apt_pin(7)
+======================
+
+NAME
+----
+cdist-type__apt_pin - Manage apt pinning rules
+
+
+DESCRIPTION
+-----------
+Adds/removes/edits rules to pin some packages to a specific distribution. Useful if using multiple debian repositories at the same time. (Useful, if one wants to use a few specific packages from backports or perhaps Debain testing... or even sid.)
+
+
+REQUIRED PARAMETERS
+-------------------
+distribution
+   Specifies what distribution the package should be pinned to. Accepts both codenames (buster/bullseye/sid) and suite names (stable/testing/...).
+
+
+OPTIONAL PARAMETERS
+-------------------
+package
+   Package name, glob or regular expression to match (multiple) packages. If not specified `__object_id` is used.
+
+priority
+   The priority value to assign to matching packages. Deafults to 500. (To match the default target distro's priority)
+
+state
+   Will be passed to underlying `__file` type; see there for valid values and defaults.
+
+
+
+BOOLEAN PARAMETERS
+------------------
+None.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+   # Add the bullseye repo to buster, but do not install any packages by default,
+   # only if explicitely asked for (-1 means "never" for apt)
+    __apt_pin bullseye-default \
+       --package "*" \
+       --distribution bullseye \
+       --priority -1
+
+    require="__apt_pin/bullseye-default" __apt_source bullseye \
+       --uri http://deb.debian.org/debian/ \
+       --distribution bullseye \
+       --component main
+
+    __apt_pin foo --package "foo foo-*" --distribution bullseye
+
+    __foo # Assuming, this installs the `foo` package internally
+
+    __package foo-plugin-extras # Assuming we also need some extra stuff

+cdist-type__download(7)
+=======================
+
+NAME
+----
+cdist-type__download - Download a file
+
+
+DESCRIPTION
+-----------
+By default type will try to use ``curl``, ``fetch`` or ``wget``.
+If download happens in target (see ``--download``) then type will
+fallback to (and install) ``wget``.
+
+If download happens in local machine, then environment variables like
+``{http,https,ftp}_proxy`` etc can be used on cdist execution
+(``http_proxy=foo cdist config ...``).
+
+To change downloaded file's owner, group or permissions, use ``require='__download/path/to/file' __file ...``.
+
+
+REQUIRED PARAMETERS
+-------------------
+url
+   File's URL.
+
+
+OPTIONAL PARAMETERS
+-------------------
+destination
+   Downloaded file's destination in target. If unset, ``$__object_id`` is used.
+
+sum
+   Supported formats: ``cksum`` output without file name, MD5, SHA1 and SHA256.
+
+   Type tries to detect hash format with regexes, but prefixes
+   ``cksum:``, ``md5:``, ``sha1:`` and ``sha256:`` are also supported.
+
+   Checksum have two purposes - state check and post-download verification.
+   In state check, if destination checksum mismatches, then content of URL
+   will be downloaded to temporary file. If downloaded temporary file's
+   checksum matches, then it will be moved to destination (overwritten).
+
+   For local downloads it is expected that usable utilities for checksum
+   calculation exist in the system.
+
+download
+   If ``local`` (default), then file is downloaded to local storage and copied
+   to target host. If ``remote``, then download happens in target.
+
+   For local downloads it is expected that usable utilities for downloading
+   exist in the system. Type will try to use ``curl``, ``fetch`` or ``wget``.
+
+cmd-get
+   Command used for downloading.
+   Command must output to ``stdout``.
+   Parameter will be used for ``printf`` and must include only one
+   format specification ``%s`` which will become URL.
+   For example: ``wget -O - '%s'``.
+
+cmd-sum
+   Command used for checksum calculation.
+   Command output and ``--sum`` parameter must match.
+   Parameter will be used for ``printf`` and must include only one
+   format specification ``%s`` which will become destination.
+   For example: ``md5sum '%s' | awk '{print $1}'``.
+
+onchange
+   Execute this command after download.
+

+cdist-type__dpkg_architecture(7)
+================================
+
+NAME
+----
+cdist-type__dpkg_architecture - Handles foreign architectures on debian-like
+systems managed by `dpkg`
+
+
+DESCRIPTION
+-----------
+This type handles foreign architectures on systems managed by
+:strong:`dpkg`\ (1). The object id is the name of the architecture accepted by
+`dpkg`, which should be added or removed.
+
+If the architecture is not setup on the system, it adds a new architecture as a
+new foreign architecture in `dpkg`. Then, it updates the apt package index to
+make packages from the new architecture available.
+
+If the architecture should be removed, it will remove it if it is not the base
+architecture on where the system was installed on. Before it, it will purge
+every package based on the "to be removed" architecture via `apt` to be able to
+remove the selected architecture.
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+state
+    ``present`` or ``absent``. Defaults to ``present``.
+
+
+MESSAGES
+--------
+added
+   Added the specified architecture
+
+removed
+   Removed the specified architecture
+
+
+ABORTS
+------
+Aborts in the following cases:
+
+If :strong:`dpkg`\ (1) is not available. It will abort with a proper error
+message.
+
+If the architecture is the same as the base architecture the system is build
+upon it (returned by ``dpkg --print-architecture``) and it should be removed.
+
+It will fail if it can not execute :strong:`apt`\ (8). It is assumed that it is
+already installed.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+  # add i386 (32 bit) architecture
+  __dpkg_architecture i386
+
+  # remove it again :)
+  __dpkg_architecture i386 --state absent
+
+
+SEE ALSO

+
+`How to setup multiarch on Debian <https://wiki.debian.org/Multiarch/HOWTO>`_
+
+:strong:`dpkg`\ (1)
+:strong:`cdist-type__package_dpkg`\ (7)
+:strong:`cdist-type__package_apt`\ (7)
+
+Useful commands:
+
+.. code-block:: sh
+
+   # base architecture installed on this system
+   dpkg --print-architecture
+
+   # extra architectures added
+   dpkg --print-foreign-architectures
