I'm quite surprised to see that OpenServer is still on that list, and Solaris isn't...

I think that IBM z/OS is the strangest entry on the list. It’s also notable that Hawaii EulerOS is a Linux distro based on CentOS

  So Huawei got Unix certification for Linux? If so, that’s a pretty big deal!

    They did, but (IIRC, and this is an old memory) to make GNU/Linux pass certification you have to hack it up quite a bit; lots of GNU tools have POSIX modes that significantly change how they behave - things like du defaulting to 1024-byte units by default but using 512-byte units if you set POSIXLY_CORRECT because parts of the standard are, um, "interesting". But yes, neat to know that it can be done.

    AFAIR, Red Hat once had a version of their system certified, too. But it's not as useful as one might think - the certification applies to a specific distro and release only, so it needs to be renewed with every new release.

Extra funny considering that Solaris is built from actual AT&T UNIX™ code and OpenServer was, last I looked, FreeBSD with some patches. (Or, honestly, sad; RIP Sun.)

  Depends on the version of OpenServer. Up to 6 (released in 2005) it was a descendant of Xenix, so plenty of AT&T (well Bell Labs I guess) code still in there probably. Later on SCO finally died and Xinuos got the trademark, which was reused for a FreeBSD-derived product as well

It's honestly a little weird that Oracle doesn't see the value in continuing to have Solaris certified, same with Redhat and RHEL, but Apple continue to get macOS certified.

  At this point Solaris is a zombie product that's only still on sale to bring in revenue from people who're so committed to the platform they'll buy it no matter what. The development team was basically disbanded a while back, and the hardware team even further back than that, and any customer who's not going to be put off by that seems fairly unlikely to be put off by the lack of certification.
