cconn a transparent connection wrapper

cconn used the inventory system to dynamically connect to FreeBSD jail via
the host system and/or using sudo to get root access

This is more of a prove of concept then a finish idea.

+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.

 -----------
 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``.

+========================
+
+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
+
+    # Same as above, but more explicit
+    __localedef de_CH.UTF-8 --state present
+
+    # Remove colourful British English
+    __localedef en_GB.UTF-8 --state absent
+

+==========================
+
+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}"}'
+
+
+SEE ALSO
+--------
+:strong:`sshd_config`\ (5)
+
+
+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.
+- | The explorer will incorrectly report ``absent`` if OpenSSH internally
+    transforms one value to another (e.g. ``permitrootlogin prohibit-password``
+    is transformed to ``permitrootlogin without-password``).
+  | Workaround: Use the value that OpenSSH uses internally.

+
+# cconn is a transparent wrapper that allows seamless usage of sudo/rsync and
+# FreeBSD jails, this makes it possible to configure a FreeBSD by just using
+# the host system sshd. 
+# Configuration is done by throw the cdist invertory system.
+#
+#
+# Installation:
+#
+# Simply set this script as remote_exec and remote_copy implementation in your
+# cdist.cfg. You MUST always pass either copy or exec as the first parameter
+# to this script
+#
+# remote_exec = path/to/cconn exec
+# remote_copy = path/to/cconn copy
+#
+# As cconn uses the cdist inventory system for host specific configuration, it
+# ether need to be executed from the directory the contains the inventory
+# directory or be setting the INVENTORY environment variable to path were the
+# inventory entries are kept.
+#
+# Usage:
+# 
+# To setup a host to use some form of connection "bending" (e.g. sudo) you need
+# to add a single __cconn_options tag to the host inventory file. Options are always a
+# key value pair separated by a '='. All options are passed in a single tag and
+# a separated by a space.
+#
+# __cconn_options options:
+#
+# NOTE: jail_host and iocage_jail can not be used at the same time and will
+# lead to a error
+#
+# jail_host: 
+#    hostname on which the FreeBSD jail resides on. 
+#
+# iocage_host:
+#    Same as jail_host, but for jails managed by iocage(8)
+#
+# jail_name:
+#    By default cconn will use the __target_host as the FreeBSD jail name, set
+#    this option to override this name
+#
+# sudo_user:
+#    Username used to connect to the __target_host, all commands are then
+#    prefixed with sudo and copy operations are done with rsync
+#
+#    For this work you need to be able to execute all command without password entry.
+#    sudoers(5)
+#    %wheel ALL=(ALL) NOPASSWD: ALL
+#
+#Examples: 
+#
+# inventory/jail.example.com:
+#     some_other_tag
+#     __cconn_options jail_host=example.com sudo_user=ada 
+#
+
+
+#TODO: add sudo_pass and sudo_passfile option to support use without NOPASSWD
+#TODO: support SSH connection multiplexing. This requieres a patch to cdist, as
+# we need path to the tmp dir.
