-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

-On Debian and alike systems :strong:`debconf-set-selections`\ (1) can be used
+On Debian and alike systems debconf-set-selections(1) can be used
 to setup configuration parameters.
 
 
 REQUIRED PARAMETERS
 -------------------
-cf. ``--line``.
-
-
-OPTIONAL PARAMETERS
--------------------
 file
-   Use the given filename as input for :strong:`debconf-set-selections`\ (1)
-   If filename is ``-``, read from stdin.
-
-   **This parameter is deprecated, because it doesn't work with state detection.**
-line
-   A line in :strong:`debconf-set-selections`\ (1) compatible format.
-   This parameter can be used multiple times to set multiple options.
-
-   (This parameter is actually required, but marked optional because the
-   deprecated ``--file`` is still accepted.)
-
-
-BOOLEAN PARAMETERS
-------------------
-None.
+   Use the given filename as input for debconf-set-selections(1)
+   If filename is "-", read from stdin.

 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.
+   Checksum is used to decide if existing destination file must be redownloaded.
+   By default output of ``cksum`` without filename is expected.
+   Other hash formats supported with prefixes: ``md5:``, ``sha1:`` and ``sha256:``.
 
 download
-   If ``local`` (default), then file is downloaded to local storage and copied
-   to target host. If ``remote``, then download happens in target.

 NAME
 ----
-cdist-type__rsync - Mirror directories using ``rsync``
+cdist-type__rsync - Mirror directories using rsync
 
 
 DESCRIPTION
 -----------
-The purpose of this type is to bring power of ``rsync`` into ``cdist``.
+WARNING: This type is of BETA quality:
+
+- it has not been tested widely
+- interfaces *may* change
+- if there is a better approach to solve the problem -> the type may even vanish
+
+If you are fine with these constraints, please read on.
+
+
+This cdist type allows you to mirror local directories to the
+target host using rsync. Rsync will be installed in the manifest of the type.
+If group or owner are giveng, a recursive chown will be executed on the 
+target host.
+
+A slash will be appended to the source directory so that only the contents
+of the directory are taken and not the directory name itself.
 
 
 REQUIRED PARAMETERS
 -------------------
 source
-   Source directory in local machine.
-   If source is directory, slash (``/``) will be added to source and destination paths.
+    Where to take files from
 
 
 OPTIONAL PARAMETERS
 -------------------
-destination
-   Destination directory. Defaults to ``$__object_id``.
+group
+   Group to chgrp to.
 
 owner
-   Will be passed to ``rsync`` as ``--chown=OWNER``.
-   Read ``rsync(1)`` for more details.
+   User to chown to.
 
-group
-   Will be passed to ``rsync`` as ``--chown=:GROUP``.
-   Read ``rsync(1)`` for more details.
-
-mode
-   Will be passed to ``rsync`` as ``--chmod=MODE``.
-   Read ``rsync(1)`` for more details.
-
-options
-   Defaults to ``--recursive --links --perms --times``.
-   Due to `bug in Python's argparse<https://bugs.python.org/issue9334>`_, value must be prefixed with ``\``.
+destination
+    Use this as the base destination instead of the object id
 
 remote-user
-   Defaults to ``root``.
+    Use this user instead of the default "root" for rsync operations.
 
 
 OPTIONAL MULTIPLE PARAMETERS
 ----------------------------
-option
-   Pass additional options to ``rsync``.
-   See ``rsync(1)`` for all possible options.
-   Due to `bug in Python's argparse<https://bugs.python.org/issue9334>`_, value must be prefixed with ``\``.
+rsync-opts
+    Use this option to give rsync options with.
+    See rsync(1) for available options.
+    Only "--" options are supported.
+    Write the options without the beginning "--"
+    Can be specified multiple times.
+
+
+MESSAGES
+--------
+NONE
 
 
 EXAMPLES
 --------
+
 .. code-block:: sh
 
-    __rsync /var/www/example.com \
-        --owner root \
-        --group www-data \
-        --mode 'D750,F640' \
-        --source "$__files/example.com/www"
+    # You can use any source directory
+    __rsync /tmp/testdir \
+        --source /etc
+
+    # Use source from type
+    __rsync /etc \
+        --source "$__type/files/package"
+
+    # Allow multiple __rsync objects to write to the same dir
+    __rsync mystuff \
+        --destination /usr/local/bin \
+        --source "$__type/files/package"
+
+    __rsync otherstuff \
+        --destination /usr/local/bin \
+        --source "$__type/files/package2"
+
+    # Use rsync option --exclude
+    __rsync /tmp/testdir \
+        --source /etc \
+        --rsync-opts exclude=sshd_conf
+
+    # Use rsync with multiple options --exclude --dry-run
+    __rsync /tmp/testing \
+        --source /home/tester \

-============================
-
-NAME
-----
-cdist-type__snakeoil_cert - Generate self-signed certificate
-
-
-DESCRIPTION
------------
-The purpose of this type is to generate **self-signed** certificate and private key
-for **testing purposes**. Certificate will expire in 3650 days.
-
-Certificate's and key's access bits will be ``644`` and ``640`` respectively.
-If target system has ``ssl-cert`` group, then it will be used as key's group.
-Use ``require='__snakeoil_cert/...' __file ...`` to override.
-
-
-OPTIONAL PARAMETERS
--------------------
-common-name
-   Defaults to ``$__object_id``.
-
-key-path
-   ``%s`` in path will be replaced with ``$__object_id``.
-   Defaults to ``/etc/ssl/private/%s.pem``.
-
-key-type
-   Possible values are ``rsa:$bits`` and ``ec:$name``.
-   For possible EC names see ``openssl ecparam -list_curves``.
-   Defaults to ``rsa:2048``.
-
-cert-path
-   ``%s`` in path will be replaced with ``$__object_id``.
-   Defaults to ``/etc/ssl/certs/%s.pem``.
-
-
-EXAMPLES
---------
-.. code-block:: sh
-
-	__snakeoil_cert localhost-rsa \
-	    --common-name localhost \
-	    --key-type rsa:4096
-
-	__snakeoil_cert localhost-ec \

-Scan
-=====
-
-Description
------------
-Runs cdist as a daemon that discover/watch on hosts and reconfigure them
-periodically. It is especially useful in netboot-based environment where hosts
-boot unconfigured, and to ensure your infrastructure stays in sync with your
-configuration.
-
-This feature is still consider to be in **beta** stage, and only operate on
-IPv6 (including link-local).
-
-Usage (Examples)
-----------------
-
-Discover hosts on local network and configure those whose name is resolved by
-the name mapper script.
-
-.. code-block:: sh
-
-    $ cdist scan --beta --interface eth0 \
-      --mode scan --name-mapper path/to/script \
-      --mode trigger --mode config
-
-List known hosts and exit.
-
-.. code-block:: sh
-
-    $ cdist scan --beta --list --name-mapper path/to/script
-
-Please refer to `cdist(1)` for a detailed list of parameters.
-
-Modes
------
-
-The scanner has 3 modes that can be independently toggled. If the `--mode`
-parameter is not specified, only `tigger` and `scan` are enabled (= hosts are
-not configured).
-
-trigger
-  Send ICMPv6 requests to specific hosts or broadcast over IPv6 link-local to
-  trigger detection by the `scan` module.
-
-scan
-  Watch for incoming ICMPv6 replies and optionally configure detected hosts.
-
-config
-  Enable configuration of hosts detected by `scan`.
-
-Name Mapper Script
-------------------
-
-The name mapper script takes an IPv6 address as first argument and writes the
-resolved name to stdout - if any. The script must be executable.
-
-Simplest script:
-
-.. code-block:: sh
-
-  #!/bin/sh
-
-  case "$1" in
-  	"fe80::20d:b9ff:fe57:3524")
-  		printf "my-host-01"
-  		;;
-  	"fe80::7603:bdff:fe05:89bb")
-  		printf "my-host-02"
-  		;;
-  esac
-
-Resolving name from `PTR` DNS record:
-
-.. code-block:: sh
-
-  #!/bin/sh
-
-  for cmd in dig sed; do
-  	if ! command -v $cmd > /dev/null; then
-  		exit 1
-  	fi
-  done
-
-  dig +short -x "$1" | sed -e 's/.$//'
