Earlier quoted context omitted.
I meant that with a bit of snark, which might have been completely misplaced. I did realize after writing that that Solaris is still under development. But most, if not all, of the Solaris that SmartOS incorporates (and DTrace and zones, specifically) was developed in the past at Sun, which is what 'redwood631 was referring to. That's also the only Solaris that I use personally (via OpenIndiana). I will keep an eye o…
Companies don't innovate, people do. All of the technologies that illumos (and Solaris) is now known for (ZFS, Dtrace, crossbow, zones, RBAC, SMF, FMA) were developed by small teams of engineers taking charge. And nearly all of the developers of those technologies are now in the illumos community and notably not at Oracle. Specifically, Dtrace is primarily the brain child of Bryan Cantrill of Joyent (co-developed wit…
You also seem to be unaware that many of the "major features" you talk about in past releases were designed and implemented by people that are still working on Solaris today and sometimes in those same areas.
Also, I have no idea why you place kernel zones in quotes -- kernel zones was actually a massive project. Not a simple variation of existing zones technology. It provides true virtualisation of Solaris on Solaris with minimal overhead compared to alternatives.
Solaris has lots to show for five years of development if you understand the engineering effort required and even more is coming -- just wait until 11.3 and Solaris 12. You'll see things from Solaris you never expected. It's bit insulting to imply that bringing things like OpenStack to Solaris wasn't a significant effort. Many of these technologies are Linux-centric and required significant engineering effort from an architectural and technical perspective to provide an integrated solution.
Solaris also has interfaces and functionality that is not available in other Solaris-based distributions; especially in upcoming releases.
