Fuchsia is a microkernel-like OS. It strategically implements some POSIX and Unix APIs to promote software re-use. It considers itself POSIX lite. "In order to reduce the amount of source modification needed to run on Fuchsia, Fuchsia offers a POSIX compatibility layer, POSIX Lite, that this software can target. POSIX Lite is layered on top of the underlying Fuchsia System ABI as a client library. However, POSIX Lite is not a complete implementation of POSIX." In the case of Fuchsia + src/util, these heavy-weight POSIX functions shouldn't be used: - file descriptors - syslog.h - signals - process creation To differentiate POSIX Lite, which Fuchsia and all heavy-weight POSIX implementations support, add DETECT_OS_POSIX_LITE. The use case is incrementally upstreaming functionality used in downstream drivers (lavapipe, ..). Being in-tree for obvious patches helps until the full driver can be merged.
