&gt; Sl. to best someone; <i>to defeat, outwit, or win against someone</i>.<p>&gt; ...It can refer to market share like you argue, but in a broader sense, this is at least how I understood the term eating someone&#x27;s lunch.<p>It&#x27;s still a far stretch to claim that zones <i>win</i> against containers. They
could if we limited the field to just technical level, and then again, I would
need to see some arguments why they actually are <i>better</i>.<p>&gt;&gt; So, zones provide better platform because people can go back and learn Solaris? Or what?<p>&gt; No, Solaris [...] provides a better platform for learning and <i>understanding</i> UNIX.<p>You&#x27;re confusing here <i>learning</i> unix with <i>using</i> it.<p>If one was at the stage of learning, Solaris could be fine, except there&#x27;s
much less material about it for newbies (especially about rough corners and
stupid troubles, like &quot;I ran `chmod -R 777 &#x2F;&#x27;&quot; or &quot;I deleted my kernel&quot;), and
much, much less knowledgable people accessible to those newbies to learn from.<p>Now look at professional Linux sysadmins and programmers. They already have
some knowledge about their OS and they&#x27;re not likely to do a hard turn for
different OS just for the sake of &quot;understanding UNIX&quot;, as it would require
quite large effort to just get to the point where they are already with Linux.
Solaris would need to provide a really compelling function or feature to
justify this effort, and all you said is &quot;portability&quot; (which most probably
won&#x27;t be necessary in most cases) and vague notion of &quot;understanding UNIX&quot;.<p>EDIT: It was a little dishonest on my side to suggest that main selling points
of Solaris derivatives were &quot;understanding UNIX&quot; and &quot;writing portabile code&quot;.
Solaris introduced ZFS and DTrace. But while it is said that ZFS with zones
work well together, it still needs explaining why is it a <i>significantly</i>
better combination than what Linux provides, and DTrace seems like a very
distant benefit, less compelling each time a tool like Sysdig shows up.
