(GCC, glibc and binutils are missing for complicated reasons, but should be up there with Guile)&lt;p&gt;By changing (all-packages) on line 26 to:&lt;p&gt;&lt;pre&gt;&lt;code&gt;  (fold-packages (lambda (package result)
                   (if (string-prefix? &amp;quot;python-&amp;quot; (package-name package))
                       (cons package result)
                       result))
                 &amp;#x27;()))
&lt;/code&gt;&lt;/pre&gt;

This approach misses &amp;quot;end user&amp;quot; packages such as browsers and QEMU, but provides some insight into high value targets.&lt;p&gt;For end user packages, Debians &amp;quot;popularity contest&amp;quot; can be useful:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;popcon.debian.org&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;popcon.debian.org&amp;#x2F;&lt;/a&gt;</text><parent_chain><item><author>hn_throwaway_99</author><text>As others have mentioned, while this may seem like a good idea, the results are often bizarre, and it&amp;#x27;s not hard to see why - the metrics and algorithm are here: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;ossf&amp;#x2F;criticality_score#criticality-score&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;ossf&amp;#x2F;criticality_score#criticality-score&lt;/a&gt;.&lt;p&gt;That algorithm seems unnecessarily complicated and includes somewhat dubious metrics when, in my mind, the only thing that really &amp;quot;counts&amp;quot; when it comes to &amp;quot;criticality&amp;quot; are &amp;quot;how many other things use&amp;#x2F;depend on me&amp;quot;, and there are much easier ways to determine this:&lt;p&gt;1.
