These are rather old postings but I think they shed some light: --8<-------- Date: Sat Oct 12 00:27:36 BST 1996 From: [EMAIL PROTECTED], Bruce Perens <[EMAIL PROTECTED]> To: debian-announce@lists.debian.org, debian-announce@lists.debian.org Subject: Debian and POSIX DEBIAN AND POSIX Many Linux distribution creators have published statements about their committment to the POSIX standard recently. The POSIX standard is a method of assuring source-code-level compatibility across a number of different software platforms. It specifies the software interface of a Unix-like operating system. A program using the standard facilities should compile properly and run the same way on any system that complies with the standard. Linux was already close to POSIX before anyone started working on actual compliance with the standard. In the past year or so it has gotten much closer to POSIX, as some Linux distribution creators have been running POSIX compliance tests and have been feeding the bugs they find back to the authors. We thank them for this effort. Until recently it was prohibitively expensive for the Debian GNU/Linux project to participate in the POSIX effort, because there was a high fee for copies of the standard, the compliance test software, and certification by a POSIX lab. Now, the U.S. Government National Institute of Standards and Technology has released a free version of their Federal Information Processing Standard 151-2 compliance test software, which tests for compliance with a superset of POSIX. They decided to make that software free so that more people would implement POSIX, and we applaud that decision. We got right to work on Debian's POSIX compliance. We currently plan to provide the capability for end-user verification - you can run the POSIX test suite on your own system if you like. There will be several POSIX-compliant Linux distributions available under the GPL. Debian GNU/Linux is the only one that's made by a non-profit organization rather than a for-profit concern. Our team of 110 volunteer developers have built a system that's equal to or better than any Linux distribution you can find. As always, we invite all organizations, for-profit and non-profit, to derive their systems and software from Debian GNU/Linux and to participate in the Debian development effort. In this way, you can acquire a POSIX-compliant base upon which you can add value. You don't need our permission to distribute and sell Debian, you need only comply with the software licenses of the programs it contains. This offer is even open to the developers of other Linux distributions.

Just my CHF 0.02: I suppose that the POSIX-compliance test is relatively cheap[1] in comparison to the XPG4 branding (afterward the branding are allowed to call your ``Un*x''-clone a ``Unix'' [note the capitalization]). I don't know how much the POSIX compliance testing actually costs, but buying the standards is affordable[2] (quoting IEEE 1996 catalog): member list 1003.1b-1993 (POSIX.1, C-API, Realtime extension) $68.40 $114.00 1003.2d-1994 (POSIX.2, Shell&Utilities, Amendment 1) $40.08 $68.00 1003.3-1991 (Test methods for measuring conformance to POSIX) $22.20 $37.00 [skipping FORTRAN] 9945-1:1990(E) (POSIX.1, C-API f.

[1] extrapolating from the standard prices [2] at least if you are a member, they are still cheap compared to the ISO/ITU-T prices...
