Recently, it seems that the objectives of the OS have shifted.
Historically, for a dozen years, the objective has been to be a Unix-work alike
and to conform strictly to the requirements of a Unix system as specified at
OpenGroup.org. This is still stated pretty clearly in the INVIOLABLES.md:
## Strict POSIX compliance
- Strict conformance to the portable standard OS interface as defined
at
OpenGroup.org.
- A deeply embedded system requires some special support. Special
support must be minimized.
- The portable interface must never be compromised only for the sake of
expediency.
- Expediency or even improved performance are not justifications for
violation of the strict POSIX interface.
Today, I think that objective has morphed; the OS is now treated like a
Linux work-alike system. That is not necessarily bad, it is just a different
objective. The only "bad" thing about this is that it happened with no
conscious consent of the community.
As a standard, Unix-like OS, inclusion of non-standard Linux interfaces is
inappropriate; as a Linux work-alike OS, it is almost mandatory to include
these non-standard interfaces. Being another Linux clone is not a very lofty
objective for an OS although it many be practical for businesses who want to
host Linux applications on NuttX.
