<p><cite>image-minimizer</cite> is a script used as an interpreter for kickstart <cite>%post</cite>
sections. It is used to remove rpm packages and individual files from the
system that Anaconda has just installed.</p>
<p>It processes a list of commands that tell it which files or rpms to remove, and
which to keep.</p>

<h2>NOTES<a class="headerlink" href="#notes" title="Permalink to this headline"></a></h2>
<p>You cannot pass any arguments to <cite>image-minimizer</cite> when using it from the
kickstart <cite>%post</cite>.</p>
<p>When using this from a kickstart the image-minimizer package needs to be available.
It is not included on the standard boot.iso, so you will need to include <cite>lorax</cite> in
the <cite>%package</cite> section. You can use <cite>image-minimizer</cite> to remove lorax from the install.</p>
<p>If you are using this with <cite>livemedia-creator</cite> it can be installed on the host
system so that <cite>lorax</cite> isn't needed in the <cite>%package</cite> list, and it doesn't need
to be removed.</p>
</section>
<section id="commands">
<h2>commands<a class="headerlink" href="#commands" title="Permalink to this headline"></a></h2>
<p>Commands are listed one per line, followed by a space, and then by the
package, file, or glob. The globs used are Unix style pathname patterns using
<cite>*</cite>, <cite>?</cite>, and <cite>[]</cite> character ranges. globbing is implemented using the python
glob module.</p>
<ul class="simple">
<li><p>drop &lt;PATTERN&gt;
This will remove files from the installation.</p></li>
<li><p>keep &lt;PATTERN&gt;
This will keep files, and should follow any <cite>drop</cite> commands including globs.</p></li>
<li><p>droprpm &lt;PATTERN&gt;
Remove matching rpm packages. Dependencies are not remove, just individual
packages matching the glob.</p></li>
<li><p>keeprpm &lt;PATTERN&gt;
Do not remove matching rpm packages, it should follow any <cite>droprpm</cite> commands
that include globs.</p></li>
