cdist-config-layout - Usage of paths in cdist
DESCRIPTION
-----------
If not otherwise specified, all paths are relative to the configuration
directory, which is normally /etc/cdist (but can be changed using environment
variables, see cdist-environment(7)).
- manifests/init:
This is the central entry point used by cdist-manifest-init(1).
It is an executable (+x bit set) shell script that can use
values for the explorers to decide which configuration to create
for the specified target host.
It should be primary used to define mapping from configurations to hosts.
- manifests/*: All other files in this directory
Cdist does not use them directly, but you can seperate
configuration mappings, if you have a lot of code in the manifest/init
file. This may also be very helpful to have different admins maintain
different groups of hosts.
- explorers/<name>
Contains explorers to be run on the target hosts, see cdist-explorers(7).
- types/
Contains all available types, which are used to provide
some kind of functionality. See cdist-stages(7).
- types/<name>/init:
Used to generate additional objects from a type.
See cdist-stages(7), cdist-types(7).
- types/<name>/gencode:
Used to generate code to be executed on the client.
See cdist-types(7).
- cache/
The cache contains results from previous runs, which may also
be used in types to gather information about other hosts
(like ssh-keys).
- cache/
- tmpdir: Temporary storage
A tempdir and a tempfile is provided by cdist-config(1), which
will be removed when the scripts ends automatically.
- tmpdir/cache/: New cache
This directory contains elements for the new cache of the host.
If all stages are completed successfully, the new cache is used
to replace the previous one.
- tmpdir/explorers/: Output of explorers
If the run was successful, the results are copied into the new cache.
- tmpdir/objects/: Objects created during run
If the run was successful, the results are copied into the new cache.

Differences manifests vs. types
manifests types
main purpose map config to host provide functionality
can change config no (prevent conflicts) yes (allow inheritance)
specificness site specific (globally) reusable

unsorted: cache / objects
- If cdist encounters type in manifest,
a wrapper script is run, that creates a
new entry in the cconfig database and adds
attribute values. This defines a cconfig
tree, that may look as follows:
<hostname>/<type>/<id>/<parameters>:
myhost/__file/cdist_bin/source
myhost/__file/cdist_bin/destination
