&gt; Secondly, they are mixing their own binary packages with binary packages from Debian and Ubuntu without rebuilding the latter. This creates something that we in Debian call a &quot;FrankenDebian&quot; which results in system updates becoming unpredictable<p>This is interesting because Debian itself encourages derivative projects to use their binary packages[1]:<p>&gt; For those derivatives that re-use Debian binary packages, add some source packages and modify some source packages, where possible we encourage them to use standard Debian mirrors and add a second repository containing only the source and binary packages that have been added or modified.<p>Or maybe they don&#x27;t encourage that behaviour but still give guidelines in case you want your derivative to work that way? I&#x27;m not 100% sure.<p>[1] <a href="https:&#x2F;&#x2F;wiki.debian.org&#x2F;Derivatives&#x2F;Guidelines" rel="nofollow">https:&#x2F;&#x2F;wiki.debian.org&#x2F;Derivatives&#x2F;Guidelines</a>
