&gt; Good idea, but won&#39;t work retroactively out of the box. So you&#39;d need a helper script to figure out your current state (using portage version and tree snapshot maybe), then prepare the environment to upgrade<br>

&gt; (and how do you handle the &quot;common&quot; case of python 2.5 only which doesn&#39;t allow newest portage anyway?)<br>
&gt;</p>
<p>Does it really need to be automated?  Why not just have a big howto that we append to whenever we break @system upgrades?  The top would have a table telling you where to start based on portage version or whatever. </p>

<p>The howto would contain links to portage and bindist snapshots (just what you need to upgrade - maybe binary pkgs, maybe not).  Then it would have a list of steps to follow. </p>
<p>If you are three years out of date it would be a long journey, but it should work. I don&#39;t think we need to make it a trivial upgrade, just a workable one. </p>
<p>And as far as extracting stage3s go - I&#39;ve done it before in a pinch, but I usually pick and choose individual files to keep it under control...</p>
