 <p>The JCR installer provider can be configured with weighted paths which are scanned.
By default, the installer scans in <em>/apps</em> and <em>/libs</em>
where artifacts found in <em>/apps</em> get a higher priority. The installer does
a deep scan and uses a regular expression to detect folders containing artifacts to be installed.
By default, artifacts from within a folder named <em>install</em> are provided
to the OSGi installer.</p>
 <p>If such an install folder contains a binary artifact (e.g. a bundle) this is provided
to the OSGi installer. In addition a node of type <em>sling:OsgiConfig</em> is
provided as a configuration to the installer.</p>
-<p>The jcr installer provider does not check or scan the artifacts itself, the detection
and installation is deferred to the OSGi installer.</p>

 <h3 id="runmode-support">Runmode Support<a class="headerlink" href="#runmode-support"
title="Permanent link">&para;</a></h3>
 <p>The JCR installer supports run modes for installing artifacts. By default folders
named <em>install</em> are checked for artifacts. If Apache Sling is started with
one (or more run modes), all folders named <em>install.[RUNMODE]</em> are scanned
as well. To be precise, the folder name can be followed by any number of run modes separated
by comma. For example, if started with run modes <em>dev</em>, <em>a1</em>,
and <em>public</em>, folders like <em>install.dev</em>, <em>install.a1</em>,
<em>install.public</em> are searched as well as <em>install.dev.a1</em>,
or <em>install.a1.dev</em>.</p>
 <p>Artifacts from folders with a run mode get a higher priority. For example by default,
an <em>install</em> folder underneath <em>/libs</em> gets the priority
<em>50</em>. For each run mode in the folder name, this priority is increased
by <em>1</em>, so <em>install.dev</em> has <em>51</em>
and <em>install.a1.dev</em> is <em>52</em>.</p>
+<h2 id="write-back-support">Write Back Support<a class="headerlink" href="#write-back-support"
title="Permanent link">&para;</a></h2>
+<p>The JCR installer supports writing back of configurations which are changed by some
other ways, e.g by using the Apache Felix web console. If this is a new configuration which
was not originally stored in the repository, a new configuration is stored under <em>/apps/sling/install</em>.
The highest search path is used together with a configurable folder (<em>sling/install</em>
in this case).
+If a configuration is changed which already exists in the repository, then it depends where
the original configuration is stored. If its under <em>/libs</em> a new configuration
at the same path under <em>/apps</em> is created. Otherwise the configuration
is directly modified.
+As JCR properties do not support all Java primitive types like Integer, the write back does
not generate a node in the repository but a properties file.</p>
+<p>Write back can be turned off by configuration.</p>

 <p>If the parent folder of a bundle has a name which is a number, this is used as the
start level (when installing the bundle for the first time, compare with <a href="https://issues.apache.org/jira/browse/SLING-2011">SLING-2011</a>).
So e.g. a bundle in the path <code>/libs/sling/install/15/somebundle.jar</code>
is having the start level <strong>15</strong>. </p>
