+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.

+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

+
+REQUIRED PARAMETERS
+-------------------
+mode
+    What mode the hardware clock is in.
+
+    Acceptable values:
+
+    localtime
+        The hardware clock is set to local time (common for systems also running
+        Windows.)
+    UTC
+        The hardware clock is set to UTC (common on UNIX systems.)
+
+
+OPTIONAL PARAMETERS
+-------------------
+None.
+
+
+BOOLEAN PARAMETERS
+------------------
+None.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Make the operating system treat the time read from the hwclock as UTC.
+    __hwclock --mode UTC

+====================
+
+NAME
+----
+cdist-type__ipset - Manage ipset sets
+
+DESCRIPTION
+-----------

+
+REQUIRED PARAMETERS
+-------------------
+type
+    One of the supported ipset set types, for a full list see:
+
+        ``ipset help``
+
+OPTIONAL PARAMETERS
+-------------------
+add
+    The entry that must exist in the given set.
+
+    Can be used multiple times.
+del
+    The entry that must not exist in the given set.
+
+    Can be used multiple times.
+state
+    Can be:
+
+    - ``present``: ensure that the given set exists.

 -----------
 This cdist type deploys an init script that triggers
 the configured rules and also re-applies them on
-configuration.
+configuration. Rules are written from __iptables_rule
+into the folder ``/etc/iptables.d/``.
+
+It reads all rules from the base folder as rules for IPv4.
+Rules in the subfolder ``v6/`` are IPv6 rules. Rules in
+the subfolder ``all/`` are applied to both rule tables. All
+files contain the arguments for a single ``iptables`` and/or
+``ip6tables`` command.
+
+Rules are applied in the following order:
+1. All IPv4 rules
+2. All IPv6 rules
+2. All rules that should be applied to both tables
+
+The order of the rules that will be applied are definite
+from the result the shell glob returns, which should be
+alphabetical. If rules must be applied in a special order,
+prefix them with a number like ``02-some-rule``.

+cdist-type__localedef(7)
+========================
+
+NAME
+----
+cdist-type__localedef - Define and remove system locales
+
+
+DESCRIPTION
+-----------
+This cdist type allows you to define locales on the system using
+:strong:`localedef`\ (1) or remove them.
+On systems that don't support definition of new locales, the type will raise an
+error.
+
+**NB:** This type respects the glibc ``locale.alias`` file,
+i.e. it defines alias locales or deletes aliases of a locale when it is removed.
+It is not possible, however, to use alias names to define locales or only remove
+certain aliases of a locale.
+
+
+OPTIONAL PARAMETERS
+-------------------
+state
+   ``present`` or ``absent``. Defaults to ``present``.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Add locale de_CH.UTF-8
+    __localedef de_CH.UTF-8

+install-recommends
+    If the package will be installed, it also installs recommended packages
+    with it. It will not install recommended packages if the original package
+    is already installed.
+
+    In most cases, it is recommended to install recommended packages separatly
+    to control which additional packages will be installed to avoid useless
+    installed packages.

 purge-if-absent
     If this parameter is given when state is `absent`, the package is
     purged from the system (using `--purge`).

+==========================
+
+NAME
+----
+cdist-type__sshd_config - Manage options in sshd_config
+
+
+DESCRIPTION
+-----------
+This space intentionally left blank.
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+file
+    The path to the sshd_config file to edit.
+    Defaults to ``/etc/ssh/sshd_config``.
+match
+    Restrict this option to apply only for certain connections.
+    Allowed values are what would be allowed to be written after a ``Match``
+    keyword in ``sshd_config``, e.g. ``--match 'User anoncvs'``.
+
+    Can be used multiple times. All of the values are ANDed together.
+option
+    The name of the option to manipulate. Defaults to ``__object_id``.
+state
+    Can be:
+
+    - ``present``: ensure a matching config line is present (or the default
+      value).
+    - ``absent``: ensure no matching config line is present.
+value
+    The option's value to be assigned to the option (if ``--state present``) or
+    removed (if ``--state absent``).
+
+    This option is required if ``--state present``. If not specified and
+    ``--state absent``, all values for the given option are removed.
+
+
+BOOLEAN PARAMETERS
+------------------
+None.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Disallow root logins with password
+    __sshd_config PermitRootLogin --value without-password
+
+    # Disallow password-based authentication
+    __sshd_config PasswordAuthentication --value no
+
+    # Accept the EDITOR environment variable
+    __sshd_config AcceptEnv:EDITOR --option AcceptEnv --value EDITOR
+
+    # Force command for connections as git user
+    __sshd_config git@ForceCommand --match 'User git' --option ForceCommand \
+        --value 'cd ~git && exec git-shell ${SSH_ORIGINAL_COMMAND:+-c "${SSH_ORIGINAL_COMMAND}"}'
+

+
+
+BUGS
+----
+- This type assumes a nicely formatted config file,
+  i.e. no config options spanning multiple lines.
+- ``Include`` directives are ignored.
+- Config options are not added/removed to/from the config file if their value is
+  the default value.
