$HOME/.cdist
</span></dt><dd>
The standard cdist configuration directory relative to your home directory
This is usually the place you want to store your site specific configuration
</dd><dt><span class="term">
cdist/conf/
</span></dt><dd>
The distribution configuration directory
This contains types and explorers to be used
</dd><dt><span class="term">
confdir
</span></dt><dd>
Cdist will use all available configuration directories and create
a temporary confdir containing links to the real configuration directories.
This way it is possible to merge configuration directories.
By default it consists of everything in $HOME/.cdist and cdist/conf/.
For more details see cdist(1)
</dd><dt><span class="term">
confdir/manifest/init
</span></dt><dd>
This is the central entry point.
It is an executable (+x bit set) shell script that can use
values from the explorers to decide which configuration to create
for the specified target host.
Its intent is to used to define mapping from configurations to hosts.
</dd><dt><span class="term">
confdir/manifest/*
</span></dt><dd>
All other files in this directory are not directly used by cdist, but you
can seperate configuration mappings, if you have a lot of code in the
conf/manifest/init file. This may also be helpful to have different admins
maintain different groups of hosts.
</dd><dt><span class="term">
confdir/explorer/&lt;name&gt;

Contains explorers to be run on the target hosts, see cdist-explorer(7).

Contains all available types, which are used to provide
some kind of functionality. See cdist-type(7).

Default values for optional parameters.
Assuming an optional parameter name of <span class="emphasis"><em>foo</em></span>, its default value would
be read from the file confdir/type/&lt;name&gt;/parameter/default/foo.
