<h2>26.1. Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>While executing, cdist stores data to local cache. Currently this feature is
one way only. That means that cdist does not use stored data for future runs.
Anyway, those data can be used for debugging cdist, debugging types and
debugging after host configuration fails.</p>
<p>Local cache is saved under $HOME/.cdist/cache directory, one directory entry
for each host. Subdirectory path is specified by
<strong>-C/--cache-path-pattern</strong> option, <strong>cache_path_pattern</strong>
configuration option or by using <strong>CDIST_CACHE_PATH_PATTERN</strong>
environment variable.</p>
<p>For more info on cache path pattern see <strong>CACHE PATH PATTERN FORMAT</strong>
section in cdist man page.</p>

<div class="section" id="cache-overview">
<h2>26.2. Cache overview<a class="headerlink" href="#cache-overview" title="Permalink to this headline"></a></h2>
<p>As noted above each configured host has got its subdirectory in local cache.
Entries in host's cache directory are as follows.</p>
<dl class="docutils">
<dt>bin</dt>
<dd>directory with cdist type emulators</dd>
<dt>conf</dt>
<dd>dynamically determined cdist conf directory, union of all specified
