Is there a Linux distribution certified with the Single UNIX Specification? What are the primary reasons that most distributions don't get certified?

Please reopen this since there are actually Linux distros that are Unix-certified. The list of certified products can be found on the Opengroup's website. Will Linux become UNIX, instead of just UNIX Like?

Most Linux distributions are mostly POSIX compliant, but there's no formal POSIX stamp on them since nobody thinks it's a good idea to either go through that procedure, or pay the required fees, or both.
Getting a POSIX certification would mean that it would be e.g. "Debian, version 8, on amd64" that was certified. Then you'd need to certify "Debian, version 8, on powerpc" etc., and then do that again for the next release. Today only a handful of commercially available Unices are certified to be POSIX compliant in very specific configurations (release version + machine architecture). For example, Solaris 8 and 9 are UNIX 98 compliant (SUSv2) on i386 and sparc, but not on x86_64.
Instead, most free Unices (not just Linux) chooses to
- Trying to conform to POSIX.
- Document non-conformance to POSIX.
- Document extensions to POSIX.
So the "contract" between you and the OS is the manual pages rather than the POSIX standard document.
I use "POSIX" above since "POSIX:2001" was the same as "Single UNIX Specification, version 3", and if I understand things right, "POSIX:2008" and "Single UNIX Specification, version 4" is the same thing too.

POSIX is not one specification but comprises a group of approved and draft specifications. In the case of POSIX.1, it is a specific IEEE specification that corresponds to a specific version of the SUS. For example, IEEE Std 1003.-2008 (AKA POSIX.1 2008) is simultaneously The Open Group Technical Standard Base Specifications, Issue 7

@fpmurphy1 Yes, I am sloppy with my use of language when I talk about these things. Thanks for the clarification.
