- Subject: POSIX system range
-
- In a comment on the sensitive issue of UPPERCASE us lowercase, John
- Gilmore stated:
-
- "My impression was that the "new operating system" was supposed to look
- very much like the set of features-in-common to the various Unix operating
- systems. If we are trying to standardize an environment that will
- run under other operating systems, somebody better tell us quick.
- I thought the "Portable Operating System" stuff was just a legalese hack
- because we can't use the trademarked name "Unix". Was I wrong? "

-
- The POSIX effort is defining an operating system interface, the boundary
- layer between application and OS Services; not an "operating system".
- One point is that we are not trying to specify the implementation.
- We also want a portable environment that can work with various UN*X
- versions. But, it should also work with some range of hosted systems,
- and systems developed from scratch. The name POSIX is to provide a
- handle for such a thing without treading on the AT&T Trademark. However,
- The purpose is to define application portability beyond the scope of the
- language constructs, but without necessarily specifiying a specific
- implementation or specific version of system from a specific vendor.
- If we reverse the implicit question "Why not UN*X" and ask "Why not hosted?"
- it is useful. If we vary from System V or Berkeley, we would like to know,
- and have some rationale for that (or not vary); similarly if we define
- constraints that prevent hosting we should have a rationale for that,
- or not propose such constraints.
-
- For information, POSIX has been proposed as a FIPS standard,
- which would have a substaintial impact on government purchases when
- that becomes finalized, and the first US Government purchase spec for
- a POSIX system went out in Oct. So we are not concerned with minor
- legalisms, but practical solutions in the real world. If the definition
- aids significantly in this, we have done well; if not, ...
